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
#includedirective 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 withstd::. - 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.
