What is Palindrome?

#include <iostream>
#include <conio.h>
#include <string.h>
using namespace std;
int main()
{
char strn[80];

int i,j,flag=0,len;
cout<<"Enter the string:";
cin.getline(strn,80);

len=strlen(strn);

for(i=0,j=len-1;i<=(len/2);++i,--j)
{

if(strn[i]==strn[j])
flag=1;

}

if(flag)
cout<<" the given string is a Palindrome";

else cout<<"The given string is NOT a palindrome";

}
