Fundamentals of Object-Oriented Programming - C++ - Numeric Input Validation - CIN.GOOD()

The video tutorial explains how to handle input and output in programming, focusing on potential issues that may arise during the input process. It introduces a method using a while loop to ensure correct user input, validating it with if statements and handling errors with methods like CN good, clear, and ignore. The tutorial demonstrates how to manage incorrect inputs and test the program with different numeric types, ensuring only valid integers are accepted.

Explain the role of the 'cin.clear()' method in the input process.

What happens if the user enters an incorrect input during the process?
