Sample C Program To Find The Reverse Of A Number.

#include <stdio.h>
#include <conio.h>

void main()
{
    int n, a, r=0;
    clrscr();

    printf(" Enter any number to get its reverse: ");
    scanf("%d",& n);
    while(n> =1)
    {
        a = n % 10;
        r = r * 10 + a;
        n = n / 10;
    }
    printf(" Reverse = %d",r);
    getch();
}

OUTPUT:

Enter any number to get its reverse: 65
Reverse = 56

C Program To Check Whether A String Is Palindrome Or Not.

#include <stdio.h>
#include <conio.h>
#include <string.h>

int main()
{

    char a[100], b[100];
    printf(" Enter the string to check if it is a palindrome ");

    gets(a);
    strcpy(b , a);
    strrev(b);
    if (strcmp(a , b) == 0 )
        printf(" Entered string is a palindrome.\n");
    else
        printf(" Entered string is not a pailndrome.\n");
    getch();
    return 0;

}

OUTPUT:

Enter the string to check if it is a palindrome: noon
Entered string is a palindrome

C Program To Check Whether A Given No. Is Palindrome Or Not.

#include <stdio.h>
#include <conio.h>
#include <string.h>

int main()
{
    int n, reversedInteger = 0, remainder, originalInteger;

    printf("Enter an integer: ");
    scanf("%d", &n);

    originalInteger = n;

    // reversed integer is stored in variable
    while( n!=0 )
    {
        remainder = n%10;
        reversedInteger = reversedInteger*10 + remainder;
        n /= 10;
    }

    // palindrome if orignalInteger and reversedInteger are equal
    if (originalInteger == reversedInteger)
        printf("%d is a palindrome.", originalInteger);
    else
        printf("%d is not a palindrome.", originalInteger);

    return 0;
}
