Study Notes
Understanding Programs and Programming Languages
- A program consists of instructions enabling a computer to complete specific tasks.
- Programming languages are the formal languages used to create programs, enabling communication between humans and computers.
- Examples of popular programming languages include C, C++, Java, and Python.
Source Code, Object Code, and Executable Code
- Source code refers to the original set of instructions written by a programmer in a high-level or intermediate programming language, which is human-readable.
- Source code is designed for ease of reading and modification, allowing programmers to make changes without difficulty.
- Computers cannot directly process source code; they require machine code to understand and execute the instructions.
- Machine code is a lower-level code that computers can interpret and execute.
