C program to check whether input string is palindrome or not

#include<stdio.h>

#include<conio.h>

#include<string.h>

main()

{

 char word[30],word1[30];

 printf("Enter any string\n");

 scanf("%s",word);

 strcpy(word1,word);

 if(strcmp(word1,strrev(word))==0)

   {

     printf("%s is palindrome string",word);

   }

   else

    {

    printf("%s is not a palindrome string ",word);

    }

   getch();

 }

Another method:

#include <stdio.h>

#include<conio.h>

#include <string.h>

 

int main()

{

  char s[100];

  int i, len, f;

  f = 0;

 

  printf("Enter any String :  \n");

  gets(s);

 

  len = strlen(s);

     

  for(i = 0; i < len; i++)

{

if(s[i] != s[len - i - 1])

{

f = 1;

break;

} 

}

if(f == 0)

{

printf("%s is a Palindrome String", s);

}

else

{

printf("%s is Not a Palindrome String", s);

}

  getch();

}

Output:
