Study Notes
History of C++
- Developed by Bjarne Stroustrup at Bell Labs in the 1980s
- Originally called "C with Classes," later renamed to C++
- First commercial implementation in 1985
- Standardized in 1998 (C++98) and again in 2011 (C++11)
Features of C++
-
Object-Oriented Programming (OOP) principles:
- Encapsulation
- Inheritance
- Polymorphism
- Multi-paradigm language: supports OOP, imperative, and functional programming
- Statically typed: checks for type errors at compile-time
- Compiled language: code is compiled to machine code before execution
Syntax and Basics
-
Variables and Data Types:
- Basic types:
int,char,float,double, etc. - User-defined types:
struct,class,enum, etc.
- Basic types:
-
Operators and Control Structures:
- Arithmetic operators:
+,-,*,/, etc. - Control structures:
if,switch,while,for, etc.
- Arithmetic operators:
Memory Management
- Pointers: variables that hold memory addresses
-
Dynamic Memory Allocation:
-
newanddeleteoperators -
mallocandfreefunctions (from C)
-
Functions and Classes
-
Functions:
- Functions can take arguments and return values
- Function overloading: multiple functions with same name but different parameters
-
Classes and Objects:
- Classes define data and functions that operate on that data
- Objects are instances of classes
- Constructors: special functions that initialize objects
Inheritance and Polymorphism
- Inheritance: a class can inherit properties from a base class
- Polymorphism: objects of different classes can be treated as objects of a common base class
- Virtual functions: functions that can be overridden by derived classes
History of C++

Features of C++
- C++ supports Object-Oriented Programming (OOP) principles, including:
- Encapsulation
- Inheritance
- Polymorphism
- C++ is a multi-paradigm language, supporting OOP, imperative, and functional programming
- C++ is statically typed, checking for type errors at compile-time
- C++ is a compiled language, where code is compiled to machine code before execution
Syntax and Basics
- C++ has Basic Data Types, including:
- int
- char
- float
- double
- C++ also allows for User-Defined Data Types, including:
- struct
- class
- enum
- C++ supports Arithmetic Operators, including:
-
-
-
- /
-
- C++ supports Control Structures, including:
- if
- switch
- while
- for
Memory Management
- C++ uses Pointers, which are variables that hold memory addresses
- C++ supports Dynamic Memory Allocation, using:
- new and delete operators
- malloc and free functions (from C)
Functions and Classes
- C++ functions can:
- take arguments
- return values
- C++ supports Function Overloading, allowing multiple functions with the same name but different parameters
- C++ classes define:
- data
- functions that operate on that data
- C++ objects are instances of classes
- C++ constructors are special functions that initialize objects
Inheritance and Polymorphism
- C++ supports Inheritance, where a class can inherit properties from a base class
- C++ supports Polymorphism, allowing objects of different classes to be treated as objects of a common base class
- C++ supports Virtual Functions, which can be overridden by derived classes
