I have a while true loop to force the user to input the right type of input and make sure that input is between 1-8. When I try to use !cin or cin.fail to check if the input is integer or not, my output goes on a loop forever.
// Taking amount of courses user is enrolled in
int courses = 0;
while (true)
{
cout << "How many courses do you want to take?\n If this is not the first time you are seeing this prompt,\n that means you entered a faulty input. Enter a number \n between 1 and 8.";
cin >> courses;
if (cin.fail())
{
cout << "You entered a non integer value such as Z or 0.2\n. Please enter an integer value\n";
}
if (courses > 0 && courses<= 8)
{
cout << "You have entered " << courses << " courses\n";
break;
}
}
Could the while true loop be causing the issue and if so, how could I fix it while having the same desired effect of running until user inputs a number between 1-8.
How the output looks:
If this is not the first time you are seeing this prompt,
that means you entered a faulty input. Enter a number
between 1 and 8.You entered a non integer value such as Z or 0.2
. Please enter an integer value
How many courses do you want to take?

I had to force stop it with the stop button in the ide console.
Edit: My program works if cin.fail is not true. If user enters an integer from the beginning, the output does not loop.
