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

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!

Answer 1

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).
