Issue

I need a routine to check if a particular is a number in order to prevent a C++ program to crash. Can you please give me an example of how it should be like?

Solution

What you can do is test the value returned by cin.

int nbJoueur=0;

cout << "nombre:";

while( !(cin >> nbJoueur) ) {

string tmp;

cinlear();

cin >> tmp;

cout << "incorrect" << endl;

}

Thanks to fiddy for this tip.
