C++ Program to Check Whether a String is Palindrome or not
In this program, you'll learn to check a given string is Palindrome or not.
A string is called Palindrome, if the original string and reverse string of original string are same.
To check if a string is palindrome or not follow below steps:
1) Declare two string: f and r.
2) Find Reverse of string.
3) Check if the reversed string is equal to the given string.
Source Code
#include<iostream>
using namespace std;
int main()
{
int f, r, len=0;
char str[20];
cout<<"Enter the string: ";
cin>>str;
// First calculate the length of string
while(str[len] != '\0')
{
len++;
}
f = 0;
r = len-1;
while(f <= r)
{
if(str[f++] != str[r--])
{
cout<<"String is not Palindrome";
return 0;
}
}
cout<<"String is Palindrome";
return 0;
}
Output
Enter the string: nitin
String is Palindrome
Enter the string: ramesh
String is not Palindrome
