C++ Tutorial - 23 - Writing on Files

[@anapaola660]

I recently found your account and I began binge-watching these videos for a refresh on C++ Thirteen years later and this is still extremely helpful. I feel as if I just struck gold. Thank you!

[@kevinaugustine]

Thanks much, Your tutorials are extraordinarily helpful for me. I am trying to navigate my way through my self taught program to learn about computers and coding- your tutorials of C++ and How to Build a Computer are greatly appreciated. I am indebted for your efforts, Kevin Walsh Chicago Peak Oil

[@Tom_Armstrong_]

Excellent tutorials, FAR easier to understand than the others I've been watching. Thanks again.

[@medatre4792]

Hi! Thank you sooooo much for this tutorial. I was on the verge of tears because I could not figure out how to "link" the text file I created. Now that I know a new one gets create it if it does not exist, I can tackle my project that is due in two hours!!!!

[@christophermwenya1484]

Almost cried as well 😂

[@LuparaAndBianca]

Tons of games have files in the folder they're in that are text files. These text files are just like part of the program but since they can be edited in real time using f.ex. notebook it means that the user can open the file, change something and the game will change accordingly. A prime example is any Minecraft server with a "server" txt document. There are a bunch of stuff you can change just by writing true or false in that document and the game will change. This is really useful.

[@thenewboston]

dont worry ill be adding another contest soon, but there are 2 other contest going on now!

[@Trolld]

come back plllz

[@FrankC656]

Bucky! Bro you should’ve seen the look on my face when I did this and it actually worked. I didn’t doubt you, just figured some how it wouldn’t be so easy.

[@Jonko192]

thanks man, very clear explanation that i couldn't find that simple on internet. Your best tut, keep up the good work

[@joanzninja4890]

Because of you im probably gonna have extra points in my project. Thanks bro.

[@bensewards]

one way to find out if you created a new file is to go to start, search, and search for the name of the file you created and if its there, there should also be any text you may have written on to the new txt file aswell! pretty cool!

[@kalef1234]

you're so good at explaining things ina short amount of time. Thanks!

[@denezt]

I like this tutorial, however I also had a small problem finding the file. But as a note you should look in your file where ever your programs are being saved to. Thanks Bucky...You rock!!! \0/

[@ss4pandaman]

thanks man you realy saved my butt i was going crazy i though my system was error or somthing then i read your note and you helped me you rock thx

[@iiN1GH7M4R3ii]

Worked well for me. I'm on Windows and Visual Studio 17. Thank you Bucky, you are very helpful!!!!!

[@BeyondAIR15]

where did you find the file?

[@iiN1GH7M4R3ii]

iNfam0usColors it's in Notepad. I found it by going to file explorer and going to My PC. Then I typed in the name of the file, waited a minute then it came up.

[@coolzidedown]

@ElPeester The file gets created in the workspace folder that the .cpp file is in. buckys was probably on the desktop

[@RondellKB]

finall a good tutorial on file hanling in c++, thanks

[@Ifindthevids]

Took me a couple of tries, but I understand this now :)

[@drcvagos-iu]

great tutorial series, thank you so much!

[@karmincernescu]

i have one question: what does the "using namespace std" do? i do some c++ programming at school, but i've never used or heard about this; thanks in advance, and thanks for sharing your c++ knowledge with us ;)

[@Harikaserap]

Thanks a lot. I did it by DownloadHelper plugin for firefox.

[@notfavoritemartian]

Nice and simple, have my like

[@Ardrin2889]

So, is there a list of the ways you can edit text such as " " for new line?

[@AlgeriaSon]

Please take a look where your folder containing Dev-C++ is located. It should be there

[@L3v1Te]

One word "awesome!"

[@MireilleNamar]

at 5:52 , this a problem i'm facing , is there anway I can add lines to a file that already has text ??

[@johnnyc130]

This looks like it be very helpful, yet i havent read anything on it. Thanks for the tutorial.

[@SajanPrasad]

Bro, by giving this, it goes and makes a file in the default place of C++. But how to make c++ store that txt or object to our specified location.

[@HardkoreRocker]

hey boston, i been working on a program for a while and im having some trouble, i need to create a file by the name thats inputted by the user......how do i do that??

[@ducarazvan94]

when will the next c++ tutorial come up?

[@tHaH4x0r]

Hello, iam not new to c++ but i have a question, what if you dont want to erase the previous "version" of the file but want to continue on the bottom ? Thanks in advance tHaH4x0r

[@carstorm85]

@Universaldark The same thing was happening to me. However when I ran a search for the file it was found in the same folder as where I had the original file saved (The c++ file)

[@Harikaserap]

Where I can download the all the videos? Thanks,

[@button4boy]

If you want to specify where to put the new file, you can write the path in the string text like this: myFile.open("C:\\Users\\Owner\\Documents\\University Stuff\\Advanced Software Development\\Assignment 2\\DataFile\\SolvedPicture.txt"); Make sure to put double backslashes in as otherwise the compiler will see them as commands etc...

[@AlphMarco]

@EMOxCORExAT try to right click it and open with and select any windows included text reader program, such as: notepad or worpad, try not to use word or so, cause the text may be different or not showing properly.

[@tadas156]

What sintax to put text files in other directories ? :)

[@johnnyc130]

How can you make a program run in the background. I want to try to use this tutorial to make a keylogger.

[@0oBadboyo0]

@coolzidedown True, found it in the workspace folder thanks.

[@BeatificStar1985]

Hey Bucky!! thanks for taking out time and putting efforts in making these tutorial !!! Kudos !!! Do you know how/where to define a path for the file created through a c++ code. Thanks again @@ !! keep up the good work!! cheers mate !!!

[@priscusemmanuel8403]

is there anyway you can help me how to do this on a Xcode?

[@surajitdas2505]

Very Helpful ..thanks :)

[@artteaparty]

What if I have a txt like this 1 2 4 0 5 6 And I want to define 2 int that each int gets one column (like x gets 1, 4 , 5 and y gets 2, 0 , 6) I need it for polynomials. i.e x is coefficient and y exponent

[@ss4pandaman]

how do i get to your website the link brings me to a video wasup with that i want to get that code you said i can get

[@JKTCGMV13]

Is it supposed to open the file, or just create it?

[@chernobila]

hello sir are you going to post more C++ tutorials? Please do Thank you

[@zetarobot]

@coolzidedown wat if the cpp file is not there?

[@pegu06]

Does this method only work for creating text files?

[@ChiefOScience]

Hey, why isnt this video on your website?

[@Universaldark]

I know this tutorial is so old, so I may not get an answer, but this never works for me. I don't know why. Has something changed with C++ in a year that causes this to not work? It's put in exactly, even brings up the command prompt, but never creates any kind of a text file. I basically typed everything in word for word, and no matter how I do it, it never brings up any text file....

[@gameglithcfinder7731]

what compiler do you use?

[@rockydasha]

new C++ Tutorial!!

[@kikegoleador315]

How can I get the user to input the location of the file along with the file name and type?

[@juliakaeppel8762]

This is a great tutorial!

[@111222333444R]

how can you do this on xcode? I don't think it's the same code. I tried it but it didn't work. :/

[@thatsmamaluigitoyou1]

is there a way to change the directory that the file will appear in other than just doing system ("cd")

[@Yizak]

Can I specify the location of the file?

[@linkinl1]

is that for new line like the endl?

[@Marty70072]

it didnt create a new file for me :/ but it ran it.. (there were no errors)

[@abboudashkar3804]

same

[@FINEDIAMOND]

How do I do this using Xcode on a Mac? I tried using "newfile.txt", but it failed because macs don't use .txt files. I tried "newfile.rtf" using Rich Text Editor, which is used to write notes in TextEdit, but it failed as well. I even tried calling one of the text files which I have saved on my computer to test it, but this didn't work either.

[@TH3L44R123]

what does this mean: C:\users\*****\desktop\happyb~1.EXE the NTVDM CPU has encountered an illegal instruction CS:0572 IP:0103 6c 75 64 65 Choose 'close' to terminate the application ?

[@papano12]

I had to save as new.cpp in the desktop location for it to work. U will get 3 new desktop icons if u save it this way. 1 of them will be the txt file. and the other 2 will be the dev project and the cmd prompt result.

[@R4G1NG]

also how can you make it only change one thing not all of the file as it will overwrite the previous thing it you just put the thing in you want to change..

[@RaamAnkka]

So i know this is like not relevant but how could this be use of? could you use it on games maybe for the save file?

[@stickmakerman]

hey dude, i got problem here. i am making a math quiz and i got the main stuff to work, but the problem is that when i am writing the points into a file with the name of the person, i want it to add it instead of replacing what's in there already. can you help a fellow subscriber? :c

[@leezhijiang]

Hey, when I run the program again, I want it to print on the next line instead of replacing the current one back. Is it possible ?

[@mrskywalker6114]

Best thing to do if you want to add to existing file is to read what's currently on it, store it in a variable(s) then add it back to the file when you overwrite it. It seems tedious work but that's how it works.

[@nilufargh]

Hey what is an object exactly? thanks

[@beterhans]

Please how to write UTF-8 text to file.

[@10000years]

i follow every step but couldn't find the txt file anywhere

[@KelechiIkegwu0]

Incase anyone has figured this out yet. The file is located where you store your cpp files. So if you didnt save on desktop it most likely will not be there :D

[@princesscatesambajon1553]

hi can i asked help? i dont know what to do with my program :(

[@GNSstudios]

i can't frekin get it to work nothing is appearing on my desktop

[@bigdogg4lyfe]

Thanks Bucky! U da man

[@Ifindthevids]

@EMOxCORExAT This confused me too, but it doesn't open the file, it just makes one, he said in the video that he was opening the file.

[@talkingfractal]

The most common thing bucky says is "Gonna wanna do" XD

[@sunnydeoloo]

great sam keep doing

[@Ardrin2889]

open() doesn't literally open the file. By "open" it means to perform input/output operations on it. So it kind of opens it, but it doesn't display it :3

[@Guildwars55]

lol but thats one of the reasons we love him

[@TheSyphon666]

thank you ^.^

[@MICHAELZHANG1997]

@savanath it's wherever you put your .cpp file

[@R4G1NG]

thank you! really needed this as i needed to help my mate edit a file and he didnt know what to change so i just sent him the .exe and he ran it and it did it for him :D if that made sence

[@ayeshahabib3060]

Sense *

[@GNSstudios]

he uses namespace. wouldnt it be easier to just not include the std: part and just do the cin.sync(); dont get angry at me in new to this juts wondering

[@GNSstudios]

Thank you.

[@thebeacongamer7286]

That's simpler than saving a file in Java!

[@lifetycoon101]

umm.....i did the exact same program except i changed the gave the text a bizarre name and it doesent work?? can any1 help?!

[@TheSyphon666]

whats a memory leak?

[@davemaze1989]

hello everyone. i cant get it to work. i nid ur help i cant get it to work on my pc. no file is been created. i have followed the steps all ova and ova, but it aint working. thanks.

[@andreuplata]

eyyy, anyone knows how to use the app option to append text instead of overwriting the previous text?? I have tried but my text turns into []

[@saigaldutt5757]

ok it did open but on a different programin language it opend in Pascal instead of note pad...whats wrong

[@DanielsThierry]

Why the hell didn't you show how to insert the next sentence under the previous one?

[@deniscimic6961]

Just do myfile.open("newfile.txt", ios::app)

[@Niki-ue6fk]

2020 still ...🌟

[@Qazqi]

cout writes to stdout. It's possible to redirect that to a file, so you can't always count on it being output to the console if the person running the program chooses otherwise. And while that is a common name for the operator, it's still the left bit shift operator, just overloaded for the purpose of output. That use has been so widespread, though, that the extra name stuck quite well.

[@Saunapa]

this code didnt create a new file. it doesnt do anything.

[@deceit1991]

Great videoo !!

[@ussul6524]

system -- not declared. Seems that you used #define

[@dominykaszakrys3373]

where the file is created, it is not on desktop

[@0xfeedcafe]

In the same folder that is your .cc/.cpp code stored

[@Loosner202]

@eeemiel You are right , thanks ! :D

[@kdwqrx]

yes you can create games with it. but there are other programming languages that can too.

[@quaget]

yeah, why don't the game software developers just come over to your house, open up notepad, and type the error report in there when your game crashes?

[@kigesui]

this is magic....

[@mjsdabeast]

you used for a new line for the first time in all of the tutorials lol

[@dsadsa9881]

@EMOxCORExAT same, myn saved it in the dev cpp file
