Compiler  Vs  Interpreter

Top 6 Differences between Compiler and Interpreter

Plus

A compiler translates programming language into machine code & creates an executable file. It requires the entire code to be compiled before the execution.

What is Compiler?

Plus

An interpreter converts program statements into machine code & executes it line by line. It does not create an executable file & requires less time to execute than a compiler.

What is an Interpreter?

Plus

 - Compiler analyzes the entire program in one go.   - The interpreter performs a line-by-line analysis on program.

Comparison based on Analysis

Plus

Comparison based on Machine Code

 - Compiler stores machine code on disk storage.   - The interpreter does not store machine code.

Plus

Comparison based on Execution

 - Compiler executes the program after the entire program is compiled.   - An interpreter executes the program after every line is evaluated, resulting in error execution line by line.

Plus

Comparison based on Error & Error execution

 - In a compiler, errors are displayed only after the entire compilation.   - In an interpreter, errors are shown line by line during execution.

Plus

 - A compiled program runs faster than an interpreted program since it consumes less time.   - An interpreted program runs slower because it consumes more time.

Comparison based on Run-Time

Plus

 - Compilation produces an output program that can run independently from source file.   - Interpretation does not produce any output program & is evaluated every time program is executed.
