Study Notes

C++ Programming Features

C++ supports multiple programming paradigms including procedural, object-oriented, and generic programming.
It includes features such as classes, inheritance, polymorphism, encapsulation, and templates, facilitating comprehensive software development.

Main Function in C++

The main function serves as the entry point of a C++ program, where execution begins.
Its declaration typically takes the format int main() and can include parameters for command-line arguments.

#include Statement

The #include directive is used to include standard or user-defined header files in a C++ program.
This allows the program to access predefined classes and functions, promoting code reuse and modular programming.

Purpose of Header Files

Header files contain declarations for functions, classes, and variables, promoting better organization of code.
They facilitate the use of the Standard Template Library (STL) and other libraries by providing necessary interfaces.

using namespace std;

The statement using namespace std; allows direct access to standard library functionalities without prefixing them with std::.
It simplifies code writing by removing the need to specify the standard namespace repeatedly.

Significance of return 0;

The return 0; statement indicates successful program termination to the operating system.
Returning a non-zero value typically signifies an error or abnormal termination of the program.

int main() Declaration

The declaration int main() signifies that the main function will return an integer value.
It is essential for compliance with C++ standards, ensuring that the program can communicate its exit status.

Role of Header Files in C++

Header files enhance code maintainability and clarity by separating declarations from implementations.
They enable efficient collaboration and sharing of code across different parts of a program or among different programs.
