We Don't Do Your Homework

Welcome to Together C & C++ :wave:

We won't do your homework for you (#rules) but we are happy to help you learn and point you in the right direction.

Please send what you have so far and ask a specific question.

[fierce creek]

still the same here

what do you need help with exactly? what did you try?

[trail plover]

How to reverse a number like 456 make it 654

[fierce creek]

Do you have any idea on how you can do it ?

[trail plover]

Yeah I know the solution but idk how it works

[fierce creek]

do you know the modulo operator? %

[trail plover]

Yes

Gives remainder

[fierce creek]

what would happen if you did 456 % 10

[trail plover]

6

[fierce creek]

do you think you can work something out with that ?

[trail plover]

Next idk

Please tell me the full logic

[fierce creek]

if you do 456 % 10 you have 6 and if you do 456 / 10 you have 45 right ?

[trail plover]

Yes

[fierce creek]

you can create a new number using 6

then if you do 45 % 10 you'll get the 5
you can put it after 6 to get 65

i think you should see where this is going

try to implement something like that and comeback with code

[pine finch]

you could probably also use two arrays and a loop

[trail plover]

@pine finch I didn't study arrays still

@fierce creek @pine finch can I dm you if I have any other doubts guys?

[fierce creek]

you can just tag us here later

don't close the post

[trail plover]

Ok actually tomorrow I have exam

Thankyou

@trail plover Has your question been resolved? If so, type !solved :)

[trail plover]

@fierce creek can you explain me what is the use of return and printf statements

[fierce creek]

https://www.geeksforgeeks.org/return-statement-in-c/

https://www.geeksforgeeks.org/printf-in-c/

[fierce creek]

You can read those, they explain better than i can

;compile

#include "stdio.h"

int add(int a, int b)
{
  return a + b; // return the value of a + b to the caller
}

int main()
{
  int result = add(1, 2); 
  printf("result is : %d", result); 
}

Program Output

result is : 3
