is plaindrome

A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward. In C++, we can write a program to check if a given string is a palindrome or not. Here are the steps to do so:

1. Start by including the necessary header files, such as <iostream> for input/output operations and <string> for string manipulation.

2. Declare the main function, which is the entry point of the program.

3. Inside the main function, declare a string variable to store the input string.

4. Prompt the user to enter a string and read the input using the std::cin statement.

5. Create a variable to store the length of the input string using the length() function from the <string> library.

6. Create a flag variable to indicate whether the string is a palindrome or not. Initialize it to true.

7. Use a for loop to iterate through the characters of the string. Start with the first character and go up to half the length of the string.

8. Inside the loop, compare the characters at the current position with the characters at the corresponding position from the end of the string. If they are not equal, set the flag variable to false and break out of the loop.

9. After the loop, check the value of the flag variable. If it is still true, then the string is a palindrome. Otherwise, it is not.

10. Display the result to the user using the std::cout statement.

11. Finally, return from the main function to end the program.

That's it! The program will now check if the given string is a palindrome or not.
