C++ is a general-purpose programming language created by Bjarne Stroustrup as an extension of the C
programming language. It incorporates both high- and low-level language features and supports a variety of
programming paradigms, including procedural, object-oriented, and generic programming.
### Key Concepts in C++
1. **Basic Syntax and Structure**
- C++ programs consist of functions and classes, with the main function being the entry point.
- Syntax is largely inherited from C, with some extensions.
2. **Data Types and Variables**
- Fundamental data types: `int`, `char`, `float`, `double`, and `bool`.
- Complex data types: arrays, pointers, and references.
3. **Operators**
- Arithmetic operators: `+`, `-`, `*`, `/`, `%`.
- Relational operators: `==`, `!=`, `>`, `<`, `>=`, `<=`.
- Logical operators: `&&`, `||`, `!`.
- Bitwise operators: `&`, `|`, `^`, `~`, `<<`, `>>`.
4. **Control Structures**
- Conditional statements: `if`, `else`, `switch`.
- Loops: `for`, `while`, `do-while`.
5. **Functions**
- Declaration and definition.
- Function overloading: Same function name with different parameters.
