Stages in the program life cycle

This is the stage where programmers write source code, involving selecting programming languages and writing code logic.

The compiler converts source code into intermediate code or machine code. At this stage, the compiler performs syntax checks, type checks, and optimizes the code into a format that the machine can understand.

Link the compiled modules and libraries into a complete executable file. This stage handles symbol references and address corrections between different modules.

The program is loaded into memory and begins to execute. In this stage, the program handles actual operations such as calculations, input/output, network communication, etc.
