What is the key difference between a compiler and an interpreter. In modern times, programmers rarely encounter assemblers, but they take assembly language input and output bytes that can be directly loaded into the machines ram and executed on its processor machine code. A compiler is defined as a computer program that is equipped to transform the codes written in highlevel programming languages into machine codes. Use assembler to produce object program in machine language. If you dig deeper, though, you find some blurring between the two in fact an interpreter could translate the. There are some characteristic differences between these two powerful. The difference lies in the way they read the source code or input.

A compiler is a computer program or a set of programs that transforms source code written in a programming language the source language into another computer language the target language, with the latter often having a binary form known as object code. Firstly, the confusion was that since the preprocessor already includes the header files into the code which contains the functions, what library functions does linker link to the object file produced by the assemblercompiler. The difference between machine language and assembly language is that machine language is directly executed by a computer and assembly language is a lowlevel programming language which requires an assembler to convert to object code or.
