Write a C program to determine if the given string is a palindrome or not

2nd method.......

#include<stdio.h>

#include<string.h>

enum Boolean{false,true};

enum Boolean IsPalindrome(char string[])

{

int left,right,len=strlen(string);

enum Boolean matched=true;

if(len==0)

return 0;

left=0;

right=len-1;

/* Compare the first and last letter,second & second last & so on */

while(left<right&&matched)

{

if(string[left]!=string[right])

matched=false;

else

{

left++;

right--;

}

}

return matched;

}

int main()

{

char string[40];

clrscr();

printf("****Program to test if the given string is a palindrome****\n");

printf("Enter a string:");

scanf("%s",string);

if(IsPalindrome(string))

printf("The given string %s is a palindrome\n",string);

else

printf("The given string %s is not a palindrome\n",string);

getch();

return 0;

}

/*

Output:

****Program to test if the given string is a palindrome****

Enter a string:liril

The given string liril is a palindrome
