Question

Write a program in c to reverse of a number using recursion

Answer 1

Explanation:

include <stdio.h>

long reverse(long);

int main()

{

long n, r;

scanf("%ld", &n);

r = reverse(n);

printf("%ld\n", r);

Answer 2

#include<stdio.h>

int main(){

  int num,reverse_number;

  //User would input the number

  printf("\nEnter any number:");

  scanf("%d",&num);

  //Calling user defined function to perform reverse

  reverse_number=reverse_function(num);

  printf("\nAfter reverse the no is :%d",reverse_number);

  return 0;

}

int sum=0,rem;

reverse_function(int num){

  if(num){

     rem=num%10;

     sum=sum*10+rem;

     reverse_function(num/10);

  }

  else

     return sum;

  return sum;

}
