💡 Hint

Common Mistakes

Confusing source code with output or input.

A compiler takes the whole source code and converts it into machine code before the program runs.

2fill in blank

medium

Complete the sentence to describe how an interpreter works.

Compiler Design

An interpreter translates and executes the program [1] at a time.

💡 Hint

Common Mistakes

Thinking the interpreter translates the entire program before running.

An interpreter reads and runs the program one line at a time, translating as it goes.

Fix the error in the statement about compilers and interpreters.

Compiler Design

A compiler translates the program [1] executing it.

💡 Hint

Common Mistakes

Choosing 'while' or 'during' which describe interpreters, not compilers.

A compiler translates the whole program before execution, unlike an interpreter.

4fill in blank

hard

Fill both blanks to complete the comparison between compiler and interpreter.

Compiler Design

A compiler translates [1] program, while an interpreter translates [2].

💡 Hint

Common Mistakes

Mixing up 'whole' and 'line by line'.

A compiler translates the whole program at once, but an interpreter translates the program line by line.

5fill in blank

hard

Fill all three blanks to explain the main difference in execution between compiler and interpreter.

Compiler Design

A compiler produces [1] code that runs [2], while an interpreter runs [3] code directly.

💡 Hint

Common Mistakes

Confusing machine code with source code or mixing up speed.

Compilers create machine code that runs faster, while interpreters run source code directly, which is slower.
