Basic structure of C++ || C++ programming language

 

Structure of C++

The structure of a C++ program typically includes preprocessor directives, a main function, variable and function declarations, statements, classes and objects, and comments. C++ is a statically-typed language that supports object-oriented and generic programming paradigms.

 

Header file
Class Definition	Data member
	Member function
Main function definition

 

Preprocessor Directives: These are lines of code that start with the # symbol and are used to include header files or define constants and macros.

 

Main Function: Every C++ program must have a main function, which is the entry point of the program. It is usually defined as follows:

            int main()
{
            //program code
}

The main function can also take command-line arguments, which are passed in as parameters.

 

Declarations: Before using a variable or a function, it must be declared. Variable declarations specify the type and name of the variable, while function declarations specify the return type, name, and parameters of the function.

 

Statements: C++ statements are instructions that perform a specific action, such as assigning a value to a variable or calling a function.

 

Functions: C++ functions are used to group related code together and can be called from other parts of the program.

 

Classes and Objects: C++ supports object-oriented programming, which means that code can be organized into classes, which define the properties and behavior of objects. Objects are instances of classes that can be created and manipulated in the program.

 

Comments: Comments are used to document the code and explain its purpose. In C++, comments can be added using the // or /* */ syntax.
