I want to get an input from the user as string and compare it with its reversed valued string,if it is equal then it's a palindrome, otherwise not.But I don't know how to store the value of that reverse function in a string so that I can compare it with original one and check it for palindrome.

What I have tried:

I have tried to reverse the string but don't know how to compare it's value with the original string.

Solution 1

This is one way you can compare strings : cplusplus.com/reference : strcmp/[^] and this is one way to acquire a string from a user or file : cplusplus.com/reference : fgets/[^]. That also shows you how to store the input in a character array.

YOU need to write the code.

It would be not an efficient solution to the problem, but, using the algorithm library, you might actually reverse the string:

C++

#include <iostream>
#include <algorithm>
using namespace std;

int main()
{
  string s = "foobar";
  string r{s};
  reverse(r.begin(), r.end());
  cout << "s='" << s << "', r='" << r << "'\n";
}
