Which of the following is NOT true about functions in programming? Functions are reusable programming abstractions., Functions help reduce the complexity of writing and maintaining programs., Functions cannot make calls to other functions within the same program., Functions help break a problem into logical chunks., Once defined, a function can be called many times from different parts of a program.

Back

Functions cannot make calls to other functions within the same program.

What is one important naming convention of functions?

Back

A function name should be as descriptive as possible to indicate what the function does.

Front

Which one of the following statements about functions is TRUE:
A function can change names over the course of a program.
Code can be added or removed dynamically from a function while the program is running.
Functions can be called using different names depending on where in the program they are called.
Two functions can be given identical names as long as their code is identical.
Two functions in a single program can have different names but contain identical code.

Back

Two functions in a single program can have different names but contain identical code.

Why are parameters useful when programming?

Back

Parameters allow for more flexible, generalized behaviors in functions.

What is the most likely outcome of running the code shown in the image above? Options: It will draw a star with each side 150 pixels long. The program will stop with an error at line 3 because parameters may not be used in for loops. The program will stop with an error at line 5 because it is dividing by 0. The program will run without error, but will not draw anything.

Back

The program will run without error, but will not draw anything.

When programmers work together, what is an example of how abstraction in programming can promote collaboration?

Back

Programmers can use functions created by their partners, relying on the functionality without needing to know the specific details of how the function is implemented.
