How Can I Validate Console Input to Ensure Only Integer Values Are Accepted for Variables a, b, and c?

Validating Console Input as Integers

When developing programs that require numeric input, it's essential to ensure that only valid integer values are accepted. In your code, you aim to validate user input to accept only integer values for three variables a, b, and c.

To achieve input validation, instead of directly converting the user responses to integers, you should employ a mechanism that tests whether the input can be parsed as an integer. Consider the following steps:

string line = Console.ReadLine(); // Read user input as a string
int value;
if (int.TryParse(line, out value))
{
    // Valid integer input, store the value in the appropriate variable
}
else
{
    // Invalid integer input, handle the error gracefully (e.g., prompt the user to enter valid input)
}

By following this approach, you can ensure that the values entered by the user are valid integers, preventing errors and ensuring the correctness of your program.
