How to Fix: What exception classes are in the standard C++ library

C++ exception classes for error handling and management.

Quick Answer: Use the C++ Standard Library's built-in exceptions, such as std::runtime_error, std::logic_error, and std::invalid_argument, to handle runtime errors and invalid input.

The standard C++ library includes several exception classes that are used to handle runtime errors and exceptions. These classes are divided into two categories: those that inherit from the base class `std::exception` and those that inherit from the base class `std::runtime_error`. The former includes classes such as `std::logic_error`, `std::invalid_argument`, and `std::out_of_range`, which are used to represent logical errors, invalid arguments, and out-of-range values, respectively.

🛠️ Step-by-Step Verified Fixes

Method 1: Understanding Exception Classes

  1. Step 1: Familiarize yourself with the different exception classes in the standard C++ library, including `std::exception`, `std::logic_error`, `std::invalid_argument`, and `std::out_of_range

Method 2: Using Exception Classes Correctly

  1. Step 1: Use the `std::exception` base class to catch all types of exceptions, and then use the specific exception classes to handle different error scenarios

🎯 Final Words

By understanding and using the exception classes in the standard C++ library correctly, you can write more robust and error-free code.
