Problem C: Roller Coaster Design (coaster.c) (65 points)

Every great theme park has a signature roller coaster. In designing a roller coaster, we must decide how many trains of cars need to be placed on the track. It turns out that no more than 25% of the track can be occupied with these trains to adhere to safety regulations. Thus, if the track is 1000 feet long, and a train is 42 feet long, then up to 5 trains can fit on the track. (To see this, note that 5 trains have a total length of 210 feet, and this value is 21%, less than or equal to 25%, of the total track length of 1000 feet. Note that 6 trains would take up 252 feet, or 25.2% of the track, which is too much.)

In a train of cars, the first car is 10 feet long and all subsequent cars are 8 feet long. All cars seat up to 4 people. Since each of these values is constant, please use the following constants to store them:

#define FIRST_CAR_LENGTH 10

#define NORMAL_CAR_LENGTH 8

#define CAR_CAPACITY 4

For this program, the user will enter the total length of the track and the maximum length of the trains for the track. It is assumed that the trains formed will be as long as possible. For example, if the user enters 30 for the maximum length of the train, then the actual trains will have three cars and be of length 26, since a four car train would exceed 30 feet. Your program should calculate the number of people that can be supported on the track at one time. (Note: It may be the case that more people can be supported by making a shorter train than possible, but for this particular assignment, maximize the size of each train.)

Input Specification

1. The total length of the track will be a positive integer (in feet) less than 10000.

2. The maximum length of a train will be a positive integer in between 10 and 100.

Output Specification

Output the maximum number of passengers on the roller coaster at any one time with a single statement of the following format:

Your ride can have at most X people on it at one time.

Early Output Samples (later, Final outputs must look like Sample Runs 3 and 4)

At first, two sample outputs of running the program are included below. Note that these samples are NOT a comprehensive test.You should test your program with different data than is shown here based on the specifications given above.

Sample Run #1

What is the total length of the track, in feet?

1000

What is the maximum length of a train, in feet?

42

Your ride can have at most 100 people on it at one time.

(Note: Each train has 5 cars on it, and each car has 4 people, at most. Thus, 20 people can sit in one train. As previously established, 5 trains is the maximum for this track, so the maximum number of people this roller coaster can support is 100.)

Sample Run #2

What is the total length of the track, in feet?

1000

What is the maximum length of a train, in feet?

49

Your ride can have at most 100 people on it at one time.

Now, modify what you have written to do:

If the Maximum Length exceeds the Actual Length print a message that "Maximum Train Length has surplus of %d feet" (and if no excess, print "Maximum Length fits exactly"); secondly, embed all of this (part C) code in a FOR loop that runs N times, where N is to be (prompted for and) read in at the beginning of the program. Thus, the user will input N and then will input the track_length and train_maximum N number of times.

Given these new requirements, see Sample Runs #3 and #4. Your program must read the new input for the value of N, and must generate output similar to Sample Runs #3 and #4.

Sample Run #3

What is the value for N?
