12 views

The four types of code are: Source Code, which is human-readable instructions written by programmers; Object Code, which is the machine-readable output of source code after compilation; Executable Code, which the computer can directly execute; and Bytecode, an intermediate code used by virtual machines. Each type serves a specific role in the process of developing and running software applications.

FAQs & Answers

  1. What is source code in programming? Source code is the human-readable set of instructions written by programmers using programming languages before it is compiled or interpreted.
  2. How does object code differ from executable code? Object code is machine-readable code generated from source code after compilation, but it might need linking before becoming executable code, which the computer can directly run.
  3. What role does bytecode play in software execution? Bytecode is an intermediate code executed by virtual machines, allowing platform-independent execution by abstracting hardware specifics.
