how do I ensure that a user does not input a number less than 1 or greater than 10 in this code. int a; cin>>a;

Answer 1

a = 0; //a MUST be initialized so the while condition is true, else it will be skipped over.

cout << "Please enter a number between 1 and 10:\t";

while (a < 1 || a > 10)
{
cin >> a;

if (a < 1 || a > 10)
{
cout << "Error! Must be between 1 and 10!" << endl;
}
}

Answer 2

If (a is less than 1 OR a greater than 10) {
Throw error on user
}
else
{
do stuff
}
