5 Questions
Which of the following is a characteristic of a compiler?
Displays errors after scanning the entire program
What is a characteristic of an interpreter?
Translates the program into machine code line by line
Why is compilation relatively slow?
Due to scanning the entire program at once
Which programming languages use interpreters?
Python and JavaScript
What is a consequence of an interpreter translating the program statement by statement?
Fast execution of interpreted code
Study Notes
Compiler Characteristics
- A compiler translates the entire program into machine code before execution, making it a characteristic of a compiler.
Interpreter Characteristics
- An interpreter translates the program statement by statement, executing each statement immediately after translation, making it a characteristic of an interpreter.
Compilation Speed
- Compilation is relatively slow because the compiler needs to translate the entire program into machine code before execution.
Interpreter-Based Languages
- Programming languages that use interpreters include JavaScript, Python, and Ruby, among others.
Interpreter Consequences
- Since an interpreter translates the program statement by statement, it allows for interactive execution and debugging, and also enables dynamic modification of the program during execution.
Test your knowledge on the key differences between compilers and interpreters. Discover how they scan and translate programs, handle errors, and the speed of compilation and execution.
