WAP using a separate function to reverse a given integer number. Say 1234 converted into 4321.

#include<stdio.h>

#include<math.h>

int main()

{

    int a,b;

    printf("Enter the integer = ");

    scanf("%d",&a);

    b=reverse(a);    ///reverse function call //

    printf("\nReverse number of %d is %d ",a,b);

     printf("\n\n");

}

int reverse(int x)

{

    int i,j,k,y;

    y=0;

    i=0;

    while(x>0)

    {

      i=x%10;        /// modulos of x

      y=(y*10)+i;    /// multiply 10 to y and adding i

      x=x/10;         ///take example of 123

    }

    return y;

}
