Check Whether a Number is Palindrome or Not in C Program

Reversing in C

#include <stdio.h>
int main()
{
int n, reversedNumber = 0, remainder;

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

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

printf("Reversed Number = %d", reversedNumber);

return 0;
}

 

Palindrome in C

#include <stdio.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;
}
