Difference Between Compiler and Interpreter

    Compiler

Compiler checks the error at a time

Compiler reads the source code, outputs executable code

Translates software written in a higher-level language into instructions that computer can understand. It converts the text that a programmer writes into a format the CPU can understand.

Requires more memory

Program execution is fast and the executable result is some form of machine-specific binary code.

A compiler takes entire program and converts it into object code which is typically stored in a file. The object code is also refereed as binary code and can be directly executed by the machine after linking

Example: C, C++

    

     Interpreter

Interpreter checks the error line by line.

    The interpreter converts the source code line-by-line during RUN     Time.

Interpret completely translates a program written in a high-level language into machine level language.

Requires less memory compared to compiler.

Program execution is relatively slow compared to compiler

An Interpreter directly executes instructions written in a programming or scripting language without previously converting them to an object code or machine code.

Example: Python and Ruby
