It's nice to see that not only the first printf function prints the hello string but it also returns a value to complete the int x = code which the next printf function prints as 5 ❤

[@gaddiji]

whats nice in this?

I think this concept of interview qs type videos is very helpful, can you guys make a playlist for interview qs shorts?

Hey I am here to thank universe . The universe helped me in getting a seat in Delhi University. Four rounds had gone and I was with no seat. So I prayed to universe , trusted him , posted letters to him and finally he helped me. I am so thankful to universe.

[@ankitmishra697]

🙄 Wow bro... ❤

[@rudragajjar454]

output is: 'Hello 5' since the printf("Hello"); statement will also be executed

[@rajshaikh3448]

Bhai bilkul sahi bola

[@sky333suraj]

The format specifier %d just prints integer.

[@rudragajjar454]

@@sky333suraj yes but the 1st line of code is an assignment statement which are executed from right to left. So the RHS of the assignment which is the command printf("Hello"); is executed first and then it's return value i.e 5 is assigned to variable x

I think "hello 5" is the real answer;

Perfect bro

Didi aapne c language ko bahut achhe se detail se padhaya hai aise aap c plus plus ka padha do n. Hum aap se padhna chahte hai c plus plus. Aapke padhane ka tarika bahut achha hai achhe se samjh me aata hai.

[@pavitrakumarsahu2522]

Please c plus plus ka bhi padha do

[@harshahm0130]

Actually Output is Hello5 because basically printf primarily does its work of printing the text and count the number characters which stores in x

[@ratnajaiswal169]

Is there any way to print only number of characters not the original word in printf ??

Bhai you are right but she asked what will be printed in place of x not complete o/p

[@SubhadipBarik-ps5ii]

Wow! I am a intermediate C programmer student but literally I also think that the result will be error. As the integer variable can't store the character value. Thank you. Aise hi critical programming ka short video upload karte raho 🎉

5 because printed function returns lengthy of a string

[@Memer09157]

Let me explain that x: 5 and output : Hello5 Because In c, compiler execute first printf function then it return 5, Hello will print on execution. Then 5 will get assign to x, then last printf function print 5. As there is not any space or new line, it will print as Hello5. Printf function return the no. Of char

[@puneeth1217]

Nice explaination

[@jaykant0007]

it will print Hello5 as output, cause printf("Hello"); print Hello and printf("Hello"); has 5 characters and 5 is stored in x. So output is Hello5.

[@akashsonar6332]

These small things make big difference in interview..

[@ayushthaware344]

Hello5 is correct Output The Print statement hello will also be printed, talking about next statement, the length of HELLO that is 5 is printed after that without any space

[@divine3832]

Those who are saying it prints Hello5, try running only int x= printf("Hello"); It will give 'Hello' as output, and if you write the complete code, it will print 'Hello5', meaning, 5 is the answer that x is returning

[@mn-t8u]

Is shows error , bro int x sirf integer leta hai to int x ko ham print hello ko kaise print kr skte

[@sayuri_20]

Sis, You really motivate me to study every time I see you. I like You already.

[@kunalmahurkar271il]

This is a simple type conversation, the string is a array of character, so it will return the amount of characters it has 😊

[@Sattari_01]

Yr kitni piyri h y...AGR issy hi coding sekhi hoti to aj m programer hota😊

[@approgrammingdoor1373]

One idea to take is, when we r printing the value of x we also used "%d" which represents an int so the output will be hello5 5 = charector of str.

[@meetparmar2107]

@@AkankshaSumanofficial The code prints "Hello" and then a number on the next line. The printf("Hello ") function prints "Hello" and returns the number of characters it printed (6, including the newline ). This return value (6) is stored in the variable x. Then, printf("%d ", x) prints the value of x, which is 6.

[@VishalSingh-nn4ne]

%d indicates the integer value thats why 5 will be print

[@princepexz]

Intresting

[@shubhangiagarkar1708]

Certainly! Here's the corrected code that stores the value returned by `printf` in `x` and returns it: ```c #include int main() { int x = printf("hello"); printf("%d", x); return x; } ``` This code prints the length of the string "hello" followed by its actual length, and then returns the value of `x`. So the output will be: ``` hello5 ``` And the return value of the program will be `5`.

[@Aarya_x12]

OUTPUT (Hello5) aa rha h

[@ankitkumar-qi3cd]

correct bro, qki phle first wala printf apna Hello print krega, phir baad me next wala printf X ki value print krega :-) then output aayega Hello5

[@mukherjee.p]

There's nothing to "think" about this. If you know you know lol. You may not be able to just guess the return value out of a random function (random because you typically wouldn't use it like this) right. Typically in systems languages, they usually return the "number of bytes written" from printing or writing functions. So there's that.

[@CaptainCoder1]

Quite simple problem for those who atleast knows the function signature of printf function it return an integer which is equal to number of characters that it has successfully printed in the console screen.

[@tgayush1424]

Bring more videos like this, or make a large video like this , this types of questions come in OA , and the prefix and postfix thing also common...

[@MdRakibulhasan-dq5dh]

yes the x value is 5 .if we get this code output .than we have hello5 output

X is an variable and it's stored the statement that are *hellow world*.

Jo printable cheeje hongi unka count number print hoga Jaise isme Hello ye sare printable hain Isiliye iska answer 5 aayega However isme \0 null character bhi hai but vo printable nhi hai isiliye vo is count me nhi add hoga

[@AyoubTahlilHersi]

Int is an integer and not a character so only the number 5 will be printed as opposed to being an array of characters [ ] such as hello which is 5 characters. so printf function of hello will be printed and then the number of characters in number "5"

[@VirenderJi-gs2qs]

Indeed

[@niranjanniru4115]

its simple that you can uderstang that int datatype always return numbers
