Writing a software program requires a specific language code. High-level programming language compilers, such as C++, are used to capture integrated development environment source code, which is compiled and executed to produce the code’s outcome.

Compilers and interpreters must gain access to machine code at the hardware level, while using processor registers for necessary calculations. Thus, an interpreter converts written and executable source code into machine code, thereby delivering instructions in the system’s native or understandable language.
