Can you be my friend?

[@dineshjoshi6936]

hi sir. I couldn't understand using of unsigned with int.

[@sagarbhatt9244]

Unsigned means it doesn't contain negative value

[@lonewolfmohit]

@@sagarbhatt9244 thank you bro!🤗

[@RahulKumar-wu1cm]

Awesome lecture way of instructing is very goo5

[@nsumanth18]

Awesome explanation....I love u

[@priyankaranawat604]

Does clear all doubts without fail. Really liked it .I look forward for more such useful content videos.

[@dmohan9878]

Can you be my friend?

[@abhishekdash6678]

sir, i have a doubt.. even in c language we can deal with divide by zero error by using goto() , where the control will move to the lebel back for taking input if the denominator is zero. so can we call it exception handling ?

[@dhrumilsinhrajput99]

cool videos always

[@abhishekm1903]

Excellent work

[@shubhameditz1826]

sir, can you make a video on structure padding also.

[@karthikk9422]

Aap great hi

[@dhruvvbatra9235]

in your example when you assinged bits to d and m the whole of it will be readed in only 1 cycle or 2 cycle

[@anilsharma-cd2hq]

Sir kya hum bit field ka use only structure m hi kar sakte h. local variable m nhi?

[@jainayush650]

Great Explaination :)

[@devashishranjan8596]

thanku sir...nice explanation

[@saurabhpola865]

Definitely a worth 👍

[@vijayrathore8401]

sir in Turbo c compiler... struct Date {int d:2; int m:3; int y; }; void main () {struct Date d1={1,1,2016}; printf("%d",sizeof(d1)); getch(); } output iska 2 ke multiple aana chahiye but sir iska output 3 kyo aa raha hai??????

[@hamdanali631]

mere hisab se toh 4 bytes aana chahiye 3 toh ni yaar

[@mr.knight8967]

May be your compiler take 1 bytes for int

[@dhananjayverma9826]

thanks a lot sir!

[@Aditya-dv5wg]

So are very good

[@chandandas2041]

Awesome

[@motivatedindia-thelion2816]

Excellent sirG

[@stark_n]

Sir I made a program yesterday by using struct and there are char,int data type .But when I set the bit field I had to set max value of bit plus one.i.e when the bit field was 5 for int 30; but Ihad to use 6..why sir?plz give an answer

[@codeWithMe199]

love from Bangladesh

[@shubhamdubey7598]

error in taking value from user its says i am giving address of bit fields,,so,cant we give address of bit fields? pls explain.

[@abcd76820]

unsigned kis liye likh rhe hai? structure k andr

[@anuragvikasmishra7799]

Hi, I am following this series of videos from the beginning, and I definitely like them. I am not sure that what is this unsigned type. could you please explain that what is the use of this keyword 'unsigned' , and how it will affect the program if I do not use this.

[@anuragvikasmishra7799]

I am still unable to understand the concept. why it is necessary to use that , and what will happen if I do not write this keyword. Can you suggest any video where you have explained about it. If yes, that would be a great help in understanding this concept.

[@KerzDude]

in a signed integer, the left most bit is reserved for the sign. 0 = positive, 1 = negative. So lets say we have a signed integer that is 3 bits. 000 = 0 001 = 1 010 = 2 011 = 3 100 = -4 (due to two's compliment) 101 = -3 (due to two's compliment) 110 = -2 (due to two's compliment) 111 = -1 (due to two's compliment) so the range of a 3 bit signed integer is from -4 to 3. in an unsigned integer, the left most bit is used for the actual number. 000 = 0 001 = 1 010 = 2 011 = 3 100 = 4 101 = 5 110 = 6 111 = 7 so the range of a 3 bit unsigned integer is from 0 to 7. Use signed integers if you want to have negative values, otherwise use unsigned. If you're wondering what two's compliment is, it's how the computer represents signed integers. Say you have a signed integer represented in binary like : 1001. Since the leftmost 1 means negative, to determine what number this value is a negative of, the computer flips all of the bits: 1001 -> 0110, and then adds 1: 0110 -> 0111, which is 7. So 1001 is actually -7 in a 4 bit signed integer. Hope that helps.

Can you be my friend!?

[@kajalgupta2160]

Nice explanation

[@kuldeepsharma7499]

Sir suppose d 17 bits consume krra h or m 16 bits so 3rd chunk bhi use hoga right so d,m,y ka size 12bytes hoga rightes? But kya code optimise hoga? Ya jo memory Bina bit field use hori h vhi hogi? Kya unused bits 0 hojegi ya koi or variable use kr Sakti h?

[@farzanalam1587]

Sir 4-4 bytes krke to mil hi rha h hume..to faeda kahan hua?? Use ni kr rhe h hm poora 4 bytes but mili to hui h na hume..to wastage ni hui?

[@abhinavojha1204]

sir can you tell me how does bit field can be applied on a float data-type?

[@shubhpandey5228]

Abhinav Ojha same way bro ..

[@pravinbadgujar7228]

Why we are used unsigned int not only int? What happen when we will use only int?

[@AnimsQuest]

It means the rest bit unused and its the drawback of bitfield.

[@abhishekmaurya1170]

मुझे ये नहीं समझ आया कि हमने getch function ya fclose use nhi kiya to output kasa dikh RHA h isme

Bhai fclose sirf tb use hota hai jb hum file ke saath kaam kr rhe hote hai... Yha hun simple sa ek concept dekha rhe hai✌

sir i am sohit or hamko bit fields me problam ho raha he plese help me sir

[@shankaranand9129]

Structure padding concept is applied

[@kartikwadhawan7448]

Why did we write unsigned before the int

[@ushniksarkar6123]

Sir what if mixed type variables are used in the structure, like int char float ? So how the allotment in multiples of 4bytes changes or it remains the same ?

[@GauravSharma-ce1yb]

I also want ask the same question If you got answer then tell me also..?

Can you be my friend?

[@arpitpundir5309]

V.gud sir

[@aadi8399]

Sir every value is stored in memory as it's ASCII equivalent So how does this bit field works

[@awaizkhan1333]

Bro ASCII codes are used to represent character constants which consume 8 bit or one byte in memory in both 16 and 32 bit compiler. And here bit fields was used to reduce the size of integer constants.

[@abhaykumarmodi7365]

ASCII value is for our understanding, memory always allocated in bits or bytes format and Bit fields works on bits

[@aadi8399]

Sir actually my dout is If we store 1 then it will stored as its ASCII equivalent that is 49 it means it takes 6 bits to store

[@VinodPatel-tn1hf]

sir g which os should i use for coding ?

[@lovemyindia8225]

sir command line argument se file handling copy karna batayee c lang me

[@GauravSharma-ce1yb]

Sir hme 4-4 bytes ke multiple mein hi ku memory blocks milenge

[@bmanichander8446]

No it isn't like that as sir used unsigned int and it is a 32 bit compiler so 4-bytes ke multiple me ayega if u use float in 32-bit 8-bytes ke multiple me ayega Simply... sizeof(datatype) ke multiple

Why it uses 8 bytes of memory where 41bits

Can you be my friend?

[@jayeshpatilcj7911]

Sir I don't understand the signed and unsigned please make video on it

[@bmanichander8446]

Signed means both negative and positive combined like if u take signed int then you can assign both negative integers and positive integers to that signed variable If u take unsigned int then u will have to assign only positive integers to that variable.

#include using namespace std; struct student { int roll; char name; int dob; }s; int main() { cout

[@uditkaushik]

+Saurabh sharma see,first select that data type whose size is maximum (in your case it's 'int' because char is 1 byte) . Now assign each data type memory or blocks according to the size of that data type. i.e 4 bytes for int + 4 bytes to represent char + 4 bytes to represent dob = 12 bytes. To make it more clear to you let's take another example... suppose instead of int roll, there would have been long int roll..in that case it would have maximum size i.e 8 bytes hence the assignment of bytes in that case would be 8 bytes + 8 bytes + 8 bytes = 24 bytes. I hope it would be clear to you .

[@saurabhsharma8014]

thanx Bhai

[@pramanikamitkumar]

int roll will take 4 bytes, char name will take 1 byte but remain 3 bytes will remain vacant, as next data will store in new memory location so it will leave 3 bytes extra.
