CSE Quiz Lists and Block Coding

Why do you think lists are an essential concept in programs?

• Lists are not essential in programming because they are only used in some specific programming languages and are not a universally used concept.

• Lists are used in programs primarily for generating random numbers, which can then be used in mathematical operations to provide a unique outcome each time the program is run. This allows for more dynamic and unpredictable results in programs that require random values.

• Lists are often used in programs to store database connections, making it easier to retrieve data from a database and use it in the program's execution. This is particularly useful in large programs with complex data structures, where keeping track of multiple database connections can become difficult. Lists allow for easy and organized access to data stored in databases.

• Lists are able to store vast amounts of data elements that can be manipulated and used throughout a program. Programs can also store data in lists for organizational purposes and later use in the program’s execution.

_________ is a technique or process that manages complexity in a program or computer system. _________ “hides” details or removes duplication, allowing the programmer to focus on high-level considerations and functions rather than the rules of a programming language.

• Input

• Abstraction

• Debugging

• Booleans

It is possible to iterate backwards through a list.

• TRUE

• FALSE

Python is an example of a ________ programming language.

• text-based

• pseudocode

• proprietary

• non-syntactical

Drag these instructions into the correct order to get the car to move so that it starts at square 1 facing north and ends in the state shown in the image. Assume that the pen starts out in the down position. Squares measure 200 mm.

• drive forward 600 mm

• turn right 90 degrees

• move pen up

• drive forward for 400 mm

• drive forward for 300 mm

In the VEXCode VR version of the car activities we can move the virtual car forward a certain number of millimeters (mm). But when we programed the real cars in the Dead Reckoning activity we had to use functions that converted a distance into the units that the motors use. What units do the motors use?

• inches

• meters

• reverse spin

• degrees

Match the following

• Allows you to choose from one of the available playgrounds

• 
• Opens or closes the blocks "drawer"

• 
• Displays the Python code for this program

• 
• Displays a detailed explanation of any block

• 
• Displays the "monitor" where text is printed out

• 

Functions are like a mini-program inside of a bigger program. In the VexCode VR, what feature allows us to create functions?

• Make a Block

• while

• Lists

• repeat
