    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.
