TO CHECK WHETHER THE GIVEN STRING IS PALINDROME

AIM

      To write a C program to find whether the string is palindrome or not.

        

ALGORITHM:

 Step-1:  Start the program

Step-2:  Enter the string

Step-3:  Find the string length using the strlen() function

Step-4:  Print the string length

Step-5:  Set a loop up to the half of the string length

Step-6:  Compare every character above the middle character with the below character

              of the middle character

Step-7:  If any character equal prints the given string is palindrome

Step-8:  If the character is not equal then print the given string is not a palindrome

Step-9:  Stop

     

PROGRAM

 #include<stdio.h>

#include<stdlib.h>

void main()

{

      int len=0,i,j;

      char name[25];

      printf(“Enter the string...”);

      scanf(“%s”,name);

      while(name[len]!=’\0')

            len++;

      printf(“\n%d”,len);

      for(i=0,j=len-1;i<len/2;i++,j-)

      {

            if(name[i]!=name[j])

            {

                  printf(“\nThe given string is not a palindrome”);

                  exit(0);

            }     }}

OUTPUT

Enter the string...engineering

The given string is not a palindrome

RESULT: Thus a c program to check the given string for palindrome is executed.
