Exercise 1: Look at the program called cla9a.cpp. On the answer sheet, answer the following questions. Note that line numbers have been added to help you identify certain parts of this program.

a. Which lines of the program contain functionprototypes?

b. Which lines of the program contain the functiondefinitionof the functionPrintInfo?

c. Which line of the programactivates(calls) the functionPrintInfo?

d. Name allvoidfunctions withno parameters(if any).

e. Name allvoidfunctions withvalue parameters(if any).

f. Name allvoidfunctions withreference parameters(if any).

g. Name thelibraryfunctions (if any) used in the program.

Exercise 2: Copy the file called cla9b.cpp to your account. This program contains a function calledquadratic()that receives input arguments for a, b, c, and x and evaluates a quadratic equation of the form ax²+ bx + c for a particular value of x.

By studying the code in cla9b.cpp, answer the following questions on the answer sheet:

a. Name the parameters (function heading) for the function quadratic(). b. Name the actual arguments (the arguments in the activation statement). c. What is the return type of this function?
