Difference Between Compiler and Interpreter

Compiler VS Interpreter

A computer is a normal machine used by almost everyone. We use different programs and software for the different purpose. There is a number of software available for different jobs. The making of a software is not a very simple process. These are developed by using the machine language. The programs used for the making of the software are the converters in the simple language. These programs can convert the high-level human language to the machine language or the computer language. This work is done by the Compilers and Interpreters etc. These are able to convert the high-level language to the binary 1 and 0 languages.

Difference Between Compiler and Interpreter


The compiler works on a basic principle. It simply reads the whole program written on it. Then it converts the whole program to the machine/computer language. For this process, the compiler takes a lot of time to read the whole program or to analyze the whole program.  The compilers are generally the memory eaters. They need a lot of memory to complete their process. Because they create the object code by analyzing the program written on them. They work fast as compared to the interpreters. Because they have the very less execution time. In this process, the whole program doesn’t require to be created/compiled every time. Languages like to C and the C++ commonly used the compilers.


It does not change the source code to any kind of the intermediate code. This feature makes it the memory efficient than the compiler as well. It requires a little bit less time to analyze the whole source code. The interpreter takes the single statement or the single line and it translates it. It works step by step for the analyzing of the source code. The interpreter has made the debugging or the removal of the errors very easy and handy as well. It tells about the errors after analyzing each statement.

Difference Between Compiler and Interpreter

  • The interpreters are memory efficient while the compilers require more memory in order to do their job efficiently.
  • Compilers read and analyze the whole source code at a time. While the interpreters work step-by-step and they analyze each statement.
  • The interpreters are commonly used in the Ruby and Python languages. While the compilers are used in the C and C++ languages.
  • Debugging in the Interpreters is very easy because it reads the statements step-by-step. While the compilers read the whole program so the debugging is relatively harder than the interpreter.
