A snack bar has a frequent customer program in which every 10th purchase is free. Customers are enrolled in the program when they make their first purchase. A programmer is writing a program to implement the frequent customer program. In one code segment, cost is set to 0for every 10th purchase by a given customer. The programmer will use the procedure One word, Get Count, open parenthesis, one word, customer I D, close parenthesis , which returns the total number of purchases a customer has made since enrolling in the frequent customer program, including his or her first purchase. Which of the following code segments will set cost to 0 for every 10th purchase a customer makes after enrolling in the frequent customer program? a. count <- GetCount (customerID)
IF (count / 10 = 0)
{
cost <- 0
}

b. count <- GetCount (customerID)
IF (NOT (count / 10 = 0))
{
cost <- 0
}

c. count <- GetCount (customerID)
IF (count Mod 10 = 0)
{
cost <- 0
}

d. count <- GetCount (customerID)
IF (NOT (count Mod 10 = 0))
{
cost <- 0
}
