Compile is the act of turning human-readable code into code the machine can understand and execute. Debug is the act of finding out where in the code the application is going wrong (debug = get rid of bugs.)

Is debugging easy in compiler?

A compiler takes a lot of time to analyze the source code. ... A compiler generates the error message only after it scans the complete program and hence debugging is relatively harder while working with a compiler. Interpreters are used by programming languages like Ruby and Python for example.

What is called compiling?

A compiler is a special program that processes statements written in a particular programming language and turns them into machine language or "code" that a computer's processor uses. Typically, a programmer writes language statements in a language such as Pascal or C one line at a time using an editor.
