AP CSP Unit 5 Part 1

What is an event-driven program?

• A program that does not implement algorithms

• A program in which all portions of the code will always be executed while it is running

• A program written to respond to specified events by executing a block of code of function associated with the event

• A program that can only be run once and only have one possible outcome, regardless of the user interactions.

Which of the following is not an action a programmer should take when debugging a segment of code?

• Display the value of variables at various points during the program

• Ask a friend or collaborator to look over the code segment to see if they are able to find any errors

• Delete all the code and re-type it

• Check the names of each variable for spelling and capitalization errors

Consider the following code:

var a = 0

var b = 2

var c = 6

a = a+b

b=a+c

c=a+b

What are the values of a, b, and c after this code segment has been run?

• a= 0 b=2 c=6

• a=2 b=6 c=2

• a=2 b=2 c=8

• a= 2 b=8 c=10
