How programs are compiled or interpreted in Intro to Computing - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to show the first step in compiling a program.

Intro to Computing

source_code = read_file('program.c')
compiled_code = [1](source_code)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Choosing 'interpret' instead of 'compile' because both relate to running code.

The first step in compiling a program is to compile the source code into machine code.

2fill in blank

medium

Complete the code to show how an interpreter runs a program.

Intro to Computing

source_code = read_file('script.py')
[1](source_code)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Choosing 'compile' because it sounds similar but it is a different process.

An interpreter runs the source code directly without compiling it first.

3fill in blank

hard

Fix the error in the code that tries to compile and then run a program.

Intro to Computing

compiled_code = compile(source_code)
[1](compiled_code)

Drag options to blanks, or click blank then click option'

Ccompile

💡 Hint

Common Mistakes

Using 'interpret' which is for running source code, not compiled code.

After compiling, the program must be executed to run the machine code.

4fill in blank

hard

Fill both blanks to complete the process of compiling and running a program.

Intro to Computing

source_code = read_file('app.c')
[1]_code = [2](source_code)
run([1]_code)

Drag options to blanks, or click blank then click option'

Cinterpret

Dexecute

💡 Hint

Common Mistakes

Swapping 'interpret' and 'compile' or using 'execute' as a function.

The source code is first compiled using the compile function, then the compiled code is run.

5fill in blank

hard

Fill all three blanks to create a dictionary showing the steps of interpreting a program.

Intro to Computing

steps = {
  [1]: 'Read source code',
  [2]: 'Translate and run line',
  [3]: 'Repeat until done'
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using strings like 'step1' instead of numbers for keys.

The dictionary keys are numbers showing the order of steps: 1, 2, and 3.
