Study Notes
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.
