$2$ Write a statement $($or comment$)$ to accomplish each of the following:

a$)$ State that a program will calculate the product of three integers.

b$)$ Prompt the user to enter three integers.

c$)$ Define the variable x to be of type int and initialize it to $0.$

d$)$ Define the variable y to be of type int and initialize it to $0.$

e$)$ Define the variable z to be of type int and initialize it to $0.$

f$)$ Read three integers from the keyboard and store them in variables x$,$ y and z$.$

g$)$ Define the variable result, compute the product of the integers in the variables x$,$ y and z$,$ and use that product to initialize the variable result.

h$)$ Display "The product is$"$ followed by the value of the int variable result.

$3$ Using the statements you wrote in Exercise $2,$ write a complete program that calculates the product of three integers
