    Study Notes

    C++ Program Structure

    • A C++ program consists of a comment, preprocessor directive, namespace, and function named main.

    Preprocessor Directive

    • #include is a preprocessor directive that tells the compiler to include a file.

    Namespace

    • using namespace std; specifies which namespace to use.

    Main Function

    • int main() is the beginning of the function named main.
    • The { symbol marks the beginning of the block for main.

    Output Statement

    • cout is used to output data.
