Introduction to C++
C++ is a general-purpose, object-oriented programming language developed by Bjarne Stroustrup. It extends C language by adding features like classes, objects, polymorphism, and templates, making it suitable for system programming, game development, and software applications.
Basic Structure of C++
A C++ program consists of header files, main function, and statements.
Data Types in C++
C++ provides various data types such as int, float, char, and double.
Operators in C++
Operators in C++ include arithmetic, relational, logical, bitwise, and assignment operators.
Control Statements
Control statements direct the flow of execution in a program.C++ provides control statements like if-else, switch-case, loops (for, while, do-while).
Functions in C++
Functions allow code reusability. They can be predefined or user-defined.
Pointers in C++
Pointers store memory addresses and enable dynamic memory allocation.
Arrays and Strings
Arrays store multiple elements of the same type, while strings are arrays of characters.
File Handling in C++
C++ allows reading and writing files using fstream.
Conclusion
C++ is a powerful, high-performance programming language used in system programming, game development, and competitive programming. It combines procedural and object-oriented programming for flexibility. Its rich standard library makes development efficient. Learning C++ provides a strong foundation for other languages like Python and Java.
