Questions

1. Are variables in computer programming the same as variables in math class? Why or why not?

• No, because if variable=variable-1 if you try and solve using math, you will get 0=-1; if done with programming, it will set the variable to something new.

2. When creating a variable, what are the two types of scope a variable can have? That is, what can it affect. (Think about your options as you make a variable)

• The variable can affect all sprites scripts or just one sprite script.

3. How many values can a variable store at one time?

• One value.

4. What will the following code snippet do? Explain why it doesn’t work as intended.

• I dont know what the intent is but if you set x to y and y to x nothing has changed. All the values maintain their original status.

5. Given the following code snippet, explain what is happening.

• Value #2 and value #1 are changing positions.
