Study Notes
Overview
- C++ is a high-performance, compiled, and general-purpose programming language.
- Developed by Bjarne Stroustrup at Bell Labs in the 1980s as an extension of the C programming language.
Features
- Object-Oriented Programming (OOP): C++ supports OOP concepts such as encapsulation, inheritance, and polymorphism.
- Templates: C++ provides a template metaprogramming system that allows for generic programming.
- Memory Management: C++ allows for manual memory management through pointers, which can be error-prone but provides low-level control.
- Multi-Paradigm: C++ supports multiple programming paradigms, including procedural, object-oriented, and functional programming.
Syntax
-
Variables: Declared using the
type variable_namesyntax, e.g.,int x;. - Control Structures: If-else statements, switch statements, loops (for, while, do-while), and jump statements (break, continue, return).
-
Functions: Declared using the
return_type function_name(parameters)syntax, e.g.,int add(int a, int b);. -
Classes: Defined using the
classkeyword, e.g.,class MyClass { ... };.
Data Types
- Primitive Types: int, float, double, char, bool, etc.
- Composite Types: arrays, structures, unions, and classes.
- Pointer Types: pointers to variables, functions, and arrays.
Operators
- Arithmetic Operators: +, -, *, /, %, etc.
- Comparison Operators: ==, !=, <, >, <=, >=, etc.
- Logical Operators: &&, ||, !, etc.
- Assignment Operators: =, +=, -=, *=, /=, %=, etc.
Standard Library
- Containers: vector, list, map, set, etc.
- Algorithms: sort, find, copy, etc.
- Input/Output: cin, cout, ifstream, ofstream, etc.
- Strings: string class for working with strings.
Compiling and Running C++ Code
- Compilers: Popular C++ compilers include GCC, Clang, and MSVC.
- Linking: The process of linking object files to create an executable file.
- ** Executing**: Running the compiled and linked executable file.
