Your question did get myself into other issues like clearing the cin on fail() --

double read_input()
{
double input;
int count = 0; 
bool valid = true;
while(count != 3) {
    cout << "Enter number: " ;
    //cin.ignore(); 
    cin >> input; 
    if(cin.fail())
    {
        cout << "Wrong Input" <::max(), '\n'); 
    }
    else 
            count++;
}
return input;
}
