This is done using a throw keyword. catch − A program catches an exception with an exception handler at the place in a program where you want to handle the problem.
Why do we need to handle exceptions in C++?
Explanation: We need to handle exceptions in a program to avoid any unexpected behaviour during run-time because that behaviour may affect other parts of the program.
