Program to check whether string is palindrome or not
#include<stdio.h>
#include<string.h>
void main()
{
char s1[20], s2[20];
printf("\nEnter s1: ");
gets(s1);
/*Copy s1 contents to s2*/
strcpy(s2, s1);
/*Reverse s2*/
strrev(s2);
/*Compare s1 and s2*/
if(strcmp(s1, s2) == 0)
printf("\nString is palindrome.");
else
printf("\nString is not a palindrome");
}
Output:
case 1:
Enter s1: abcde
String is not a palindrome
case 2:
Enter s1: abcba
String is palindrome.
if(strcmp(s1, s2) == 0)
printf("\nString is palindrome.");
else
printf("\nString is not a palindrome");
}
Output:
case 1:
Enter s1: abcde
String is not a palindrome
case 2:
Enter s1: abcba
String is palindrome.
