In a simple C++ program, what keyword is used to include libraries?

What is a common mistake when writing the first C++ program?

Purpose of the First C++ Program

The primary purpose is to demonstrate the basic syntax and structure of a C++ program.
Commonly, the first program outputs "Hello, World!" to familiarize programmers with the compilation and execution process.

Essential Component of C++ Program Structure

A basic C++ program must include a function, typically main(), which serves as the entry point for execution.

Output of Basic C++ Program

A program containing cout << Hello, World!; will produce the output: Hello, World! on the screen.
The statement is part of the Standard Library, specifically used for console output.

Including Libraries in C++

The keyword #include is used to include libraries, enabling access to standard functions and objects.
For example, #include <iostream> is used to incorporate the Input/Output stream library.

Common Mistakes in First C++ Program

A frequent error is omitting the necessary std:: prefix for standard elements like cout, leading to compilation issues.
Forgetting to declare the return type for main(), which should be int, can also cause problems.

This quiz covers the fundamental concepts of writing your first program in C++. It will test your knowledge on the essential components, common mistakes, and the output of a basic C++ program. Perfect for beginners looking to solidify their understanding of C++ structure and syntax.
