Handling input errors, general question

Hello,

I'm trying to idiot-proof my program and I can't seem to figure out one part. I want to input integers for a menu system, but I get thrown into an infinite loop whenever somebody inputs a character or a string to the console. How can I stop this from happening?

I've been trying to use cin.fail() but I can't get the stream to clear back out again. Is there a reliable way to handle a problem like this?

Either make a large while or do-while statement (depends on menu size)

like

do
{
cout << "Which choice?";
cin >> My_int;
}while ((My_int != 1)&&(My_int != 2));

or

provide a default value with an if statement if your integer requirement isn't met.

You could try this -

Code:

---

#include <iostream>


using namespace std;

int main()
{
        int a;

        cin>>a;

        while(cin.fail())
        {
                cin.clear();
                cin.ignore(80,'\n');
                cin>>a;
        }


        return 0;
}
