Question

I am trying an example from Bjarne Stroustrup’s C++ book, third edition. While implementing a rather simple function, I get the following compile time error:

error: ISO C++ forbids comparison between pointer and integer

What could be causing this? Here is the code. The error is in the if line:

#include <iostream>
#include <string>
using namespace std;
bool accept()
{
    cout << "Do you want to proceed (y or n)?\n";
    char answer;
    cin >> answer;
    if (answer == "y") return true;
    return false;
}

Thanks!

You have two ways to fix this. The preferred way is to use:

string answer;

(instead of char). The other possible way to fix it is:

if (answer == 'y') ...

(note single quotes instead of double, representing a char constant).
