Thread: How to return reverse number in function

Is it possible to get reverse number in return ?

If i pass number 123 then I want the function which can give the reverse number of original number

Code:

int main ()
{
    return 0;
 }

unsigned int reverse (unsigned int number)
{
   }

it will be like this

321 reverse (123)

Is it possible ?

Actually I don't have any idea how to do it

Google will tell you: LMGTFY

you can reverae a number

Code:

 
while

Code:

(n !=0)
    {
        remainder = n%10;
        reversedNumber = reversedNumber * 10+ remainder;
        n /=10;
    }

I don't wan't to do it with modulo operators

Why not? Is this some sort of homework assignment in which you're forbidden from using the modulus operator?

I am thinking in this way because I think it's easy we can pass number and can get return number in function. I know we can do it with modulus operator and I have done it before

I am guessing the OP has no idea of how to write an function.

program

Code:

#include<stdio.h>
int reverse(int number, int returnNumber);
int main()
{
    int reverseNumber;
    
    reverseNumber = reverse(123,321);
    printf("\n reverse Number %d",reverseNumber);
    
 return(0);
}
int reverse(int number, int returnNumber)
{
    returnNumber = 321;
    return(returnNumber);
}

Reverse number is = 4926

If you don't want to use the modulo operator convert the number to a string, reverse the string and convert it back to a number.
