Understanding Compilers and Interpreters

Why do machines require source code to be converted into machine code?

• To improve the security of the code

• To enable machines to understand and execute it

• To reduce the size of the code

• To make it easier for humans to read

What is the role of an assembler in the context of low-level languages?

• It interprets code line by line

• It compiles code into object code

• It translates assembly code into binary machine code

• It converts high-level code into machine code

How does an interpreter handle high-level language code?

• It converts code into assembly language

• It translates and executes code line by line

• It compiles the entire code at once

• It creates object code for linking

What must be true for a program to be successfully compiled?

• The code must be linked with external libraries

• The code must be free of syntax errors

• The code must be written in assembly language

• The code must be executed line by line

What is object code?

• The final executable machine code

• Intermediate code produced by a compiler

• Code that is interpreted line by line

• Code written in a high-level language

What is the purpose of a linker program in the compilation process?

• To execute code line by line

• To convert code into assembly language

• To pull in pre-written code from external libraries

• To translate code into machine code

What is the result of a successful compilation?

• A syntax error report

• A line-by-line execution

• An executable machine code

• An intermediate code

What happens if there is a syntax error in a program being interpreted?

• The program runs until the error is encountered

• The interpreter skips the erroneous line

• The entire program fails to run

• The interpreter automatically corrects the error

What is a key difference between a compiler and an interpreter?

• An interpreter produces object code

• An interpreter converts code into assembly language

• A compiler translates code line by line

• A compiler requires the entire code to be error-free before execution

Which of the following is a disadvantage of using an interpreter?

• It does not allow for debugging

• It is slower due to line-by-line execution

• It requires the entire code to be error-free before execution

• It cannot handle high-level languages
