Read a string and check whether it is palindrome or not.

 //Read a string and print the string is palindrome or NOT palindrome.

#include<stdio.h>
void main()
{
char a[500],b[500];
clrscr();
printf("\n Enter A String :-  ");
scanf("%s",&a);
strcpy(b,a); //copies string a to b
strrev(b);  //reverses string b
if(strcmp(a,b)==0)  //compares if the original and reverse strings are same
printf("\n %s is a palindrome",a);
else
printf("\n %s is not a palindrome",a);
getch();
}

//Read a string and print the string is palindrome or NOT palindrome without using inbuilt functions.
