C++ Question

C++ Boolean function returning 56

I have a function to return a bool:

bool restart()
{
std::string answer;
bool answered = false;
while(answered == false)
{
cout << endl << endl << "Do you want to play again? y/n : ";
cin >> answer;
if(answer == "y" || answer == "Y" || answer == "1" || answer == "yes")
{return true;}
if(answer == "n" || answer == "N" || answer == "0" || answer == "no")
{return false;}
}
}


When I call it using:

cout << restart();


I get the output:

Do you want to play again? y/n : y
56


Can anyone see how to fix this strange problem?
Thanks in advance.

My WIP code as it is now:

#include <iostream>
#include <cstdlib>

using namespace std;

void drawScreen(int grid[3][3]); //
int movef(int grid[3][3], bool playersMove);
int updateGrid(int grid[3][3], int move, bool playersMove);
bool hasWon(int grid[3][3]);
bool swapMover(bool playersMove); //
bool restart();
void endGame();

int main()
{
int grid[3][3] = {{1,2,3},{4,5,6},{7,8,9}};
bool appRunning = true, gameRunning = true, playersMove = true;
int move;

// tests //
std::cout << restart();
// tests //

//while(appRunning == true)
//{
// while(gameRunning == true)
// {
// drawScreen(grid);
// move = movef(grid, playersMove);
// grid[3][3] = updateGrid(grid, move, playersMove);
// drawScreen(grid);
// gameRunning = hasWon(grid);
// playersMove = swapMover(playersMove);
// }
// appRunning = restart();
//}
//endGame();
}

void drawScreen(int grid[3][3])
{
for(int i = 0; i < 3; i++)
{
for(int j = 0; j < 3; j++)
{
if(grid[i][j] == 10){cout << "X ";if(j == 2){cout << endl << endl;}}
if(grid[i][j] == 11){cout << "O ";if(j == 2){cout << endl << endl;}}
if(grid[i][j] != 10 && grid[i][j] != 11){cout << grid[i][j] << " ";
if(j == 2){cout << endl << endl;}}
}
}
}

int movef(int grid[3][3], bool playersMove)
{
return 0;
}

int updateGrid(int grid[3][3], int move, bool playersMove)
{
return 0;
}

bool hasWon(int grid[3][3])
{
return false;
}

bool swapMover(bool playersMove)
{
if(playersMove == true){return false;}
if(playersMove == false){return true;}
}

bool restart()
{
std::string answer;
bool answered = false;
while(answered == false)
{
cout << endl << endl << "Do you want to play again? y/n : ";
cin >> answer;
if(answer == "y" || answer == "Y" || answer == "1" || answer == "yes")
{return true;}
if(answer == "n" || answer == "N" || answer == "0" || answer == "no")
{return false;}
}
}

void endGame()
{

}

Answer

I used the mingw32 compiler, when using g++ 4.8 it works fine. It seems to be a compiler error. (thanks to grizzly)
