Question

I’m familiar with loops, yet looping a process has left me bewildered:

If the user enters a non-integer, I would like the question ‘your age’ to be prompted again until the user enters an integer.

 Console.WriteLine("Your age:");
 string line = Console.ReadLine();
 if (!int.TryParse(line, out age))
 {
     Console.WriteLine("{0} is not an integer", line);

 }

Answer 1

Try this, it will make “Your age: “ repeat until you have correct input:

int age;
while(true)
{
    Console.WriteLine("Your age:");
    string line = Console.ReadLine();

    if (!int.TryParse(line, out age))
       Console.WriteLine("{0} is not an integer", line);

    else break;
}
