A programming language is set a of Instrucitons used to communicate with a computer.
It is used to create, software, applications, games and system programs.
1. What is a Programming Language?
2.. Types of Programming Languages
- Low-level Languages (Mchine & Assembly)
- High-Level Languages (C, C++, Java, Python)
Important: C & C++ are high-level languages.
3. What is C Language?
- Definition
- C is a high-level, structured, general-purpose programming language.
- Developed By
- Dennis Ritchie in 1972 at Bell Labs.
- Features
- Fast execution
- Portable
- Procedure-oriented
- Foundation of all modern languages
Uses of C:
- Operating Systems
- Embedded Systems
- Game Development
- System Software
4. What is C++ Language?
- Definition
- C++ is an extension of C that supports Object-Oriented Programming (OOPs)
- Developed by
- Bjarne Stroustrup in 1979.
- Features
- Object-Oriented
- Faster than Java
- Supports classes & objects
- Better memory control
Uses of C++:
- Game Engines
- Database Software
- Browsers (Chrome)
- Operating Systems
5. Difference Between C and C++
| C Language | C++ Language |
|---|---|
| Procedure-Oriented | Object-Oriented + Procedure-Oriented |
| Developed in 1972 | Developed in 1979 |
| Less Secure | More Secure(OOP features) |
6. Important Terms of C & C++
- Compiler
- Converts source code → machine code.
- Syntax
- Rules to write code.
- Variable
- Storage location with a name.
- Function
- A block of reusable code.
