I am confused about why am getting this error, here is my code:

main.cpp:

int main(int argc, char *argv[])

{

string prompt = "Please enter the r, g, and b integer values of a color, with each separated by a space (e.x., \"255 255 255\")(CTRL-D to exit) : ";

/*

Color color;

cout << "Color values after declaration : " << color.to_str() << endl;

cout << prompt;

for (int r, g, b ; ; ) {

while (!(cin >> r >> g >> b)) {

if (cin.bad() || cin.eof()) {

return 1;

} else if (cin.fail()) {

cin.clear();

cin.ignore(numeric_limits::max(), ' ');

}

cout << "Invalid input." << endl << endl << prompt;

cin >> r >> g >> b;

}

color.set_R(r); color.set_G(g); color.set_B(b);

cout << "Color : " << color.to_str() << endl << endl;

cout << prompt;

}

*/

// Part 2

cout << prompt;

for (int r, g, b ; ; ) {

while (!(cin >> r >> g >> b)) {

if (cin.bad() || cin.eof()) {

return 1;

} else if (cin.fail()) {

cin.clear();

cin.ignore(numeric_limits::max(), ' ');

}

cout << "Invalid input." << endl << endl << prompt;

cin >> r >> g >> b;

}

Color color(r, g, b);

cout << "Color : " << color.to_str() << endl << endl;

cout << prompt;

}

return 0;

}
