Question

I have a simple little script I am coding, and I am trying to not allow people to enter a string, or if they do make it revert to the beginning of the function again. Here’s the input code I have:

int main()
{
    cout << "Input your first number" << endl;
    cin >> a;
    cout << "Input your second number" << endl;
    cin >> b;
}

The rest of the code beyond this part works just fine for what’s going on, although if a string is entered here it obviously doesn’t work.

Any help would be appreciated.

Basically you can check the input, whether it is numeric value or not. After checking whether the given input is numbers, then you can add a while loop in main to ask user to repeat if input is not a valid number.
