Unit 7

Which of the following is an example of abstraction?

• Writing a function for code you repeat often
• Using logic symbols like < and >
• Numbers are converted from one base to another
• There is an error in the code

Why are parameters useful when programming?

• Parameters determine the number of times the function will run. 
• Parameters allow for more flexible, generalized behaviors in functions.
• Parameters are useful for teams of programmers because they help define the boundaries of the problem they are trying to solve. 
• Parameters change the order of operations within a function. 

Multiple functions within a program can have the same name

• True
• False

What is the correct way to call the function called "doMath" with a parameter of 5?

• doMath(5);
• function doMath(5);
• doMath();
• doMath{5};

Why do we use functions in programs?

• A.  Make the program easier to read
• B.  Avoid retyping the same lines of code
• C.  Both A and B are correct
• D. Neither A nor B are correct

What is wrong with this program?

• The "go" function is called twice

• The "go" function has a syntax error

• The "go" function has been defined twice

• "go" is not a command that can be used

A benefit of using well-named functions and parameters in a computer program is

• The program will run faster
• The program will be easier for people to read
• The program will have a greater data storage capacity
• The program will not need parameters

Functions can have data passed into them for processing. The variable that represents this data is called a(n)​ ​ (a)   , and the data provided in the function call is called a(n) ​​ (b)   .

• parameter
• argument
• list
• subroutine
• variable
• module

Data passed back to calling code when a function has completed its execution.

• Lists

• Parameters

• Subroutines

• Return Value
