A program of reverse a number using recursion in C?

Answer 1

(in C#)

string Reverse (string input) {

There are two cases; the recursive case and the trivial case.

The trivial case is when the string has zero or one character. In this case, the reversal of the string is the same.

if (input.Length <=1 ) return input;

For any other string, you can reverse it by reversing the "tail" of the string, and then putting the "head" on the end.

else return Reverse (input.Substring(1)) + input[0];

}

Answer 2

#include<stdio.h>

main()

{

int a , d=0;

clrscr();

printf("\nEnter a number that is to be reversed:");

scanf("%d",&a);

for(; a>0;)

{

d= d*10 + a%10;

a /=10;

}

printf("%d", d);

getch();

}

Answer 3

while(num!=0) { digit =num%10; rev=rev*10+digit; num=num/10; } this logic would certainly solve ur problem try it. Dnyanesh Khedekar
