Quotation marks (“ “) are used to include files that we write ourselves.

Question 5

What are triangle brackets (< >) used for?

Answer 5

Question 6

What is the run function?

Answer 6

The run function is where your code gets executed.

Question 7

Answer 8

The two triangles arranged like this are used to insert data, i.e. we are inserting the text we want to print to the STandarD C++ OUTtput.

We can write std::cout because the header file was included, which is where std::cout is declared.

Question 10

What does the ; do?

Answer 10

Question 11

What does aserveOscillator() do?

Answer 11

aserveOscillator() switches on an oscillator with the settings that are specified as its four
arguments.

Question 12

What are the 4 arguments inside aserveOscillator(a,b,c,d);?

Answer 12

a = oscillator number (0 – 23)
b = oscillator frequency (0.0 - 20000.0)
c = oscillator amplitude (0.0 - 1.0)
d = oscillator wave form (0 – 5)

Question 13

What is the oscillator function call followed by?

Answer 13

A call to aserveSleep(), which causes the program execution to pause for the time specified in milliseconds (i.e. aserveSleep(1000); pauses the program for 1 second).
