Part 1: Weekly Assessment for class.

Part 2: Weekly Assessment for lab.

Weekly Assessment 2 (Weight 15%) should be done individually.

Deadline: 12/05/2020

Write a C program to keep records and perform statistical analysis for a car sales agency. The

information of each car contains the number of the doors, the cylinder, and the width. Note that

you cannot use nested loops in the program. We consider in the program three one-dimensional

arrays named as follows:

1. door: An array to save the number of doors for each car.

2. cylinder: An array to save the number of the cylinders of each car.

3. width: An array to save the car width.

The size of all arrays used in the program is 5. Consider the constant SIZE with value equal to 5.

The values of the arrays’ elements (door[i], cylinder[i] and width[i]) represent the car’s

information with car ID’s equal to the value of the index “i”.

Part 1:

1. Write a function M_PrintArray_04 that takes an array of integers with size equal to SIZE and prints all array’s elements horizontally centered in the screen. This function should not print elements with value equal to -1 as shown in the example below. (15 points) Example: If the array contains: [2, 4, 1, -1, -1], the function should print the following: The array’s elements: 2 4 1

2. Write a function M_Max_width_04 that takes three arrays (door, cylinder and width) as formal parameters and then prints the cars’ information of the longest car(s). It could be more than one car. For example, if we have 3 cars with widths 2.2 (id =0), 2 (id =1) and 2.2 (id =2), this function should print the values of 2 cars with id = 0 and id =2. (20 points)

3. Write a function M_Count_doors_04 that takes a one dimensional array (door) as formal parameter and then calculates and returns the number of occurrence of the value 3 in the array door. (10 points)

Part 2:

4. Write a function M_DrawRectangle_04 that displays the below rectangle (row = 5 and column = 10) horizontally centered in the screen by using a for loop as shown in figure 1. (25 points)

5. Write a main function that does the following: (30 points) – Define and initialize three one-dimensional arrays named door, cylinder and width with the

value -1. The value -1 means that the agency didn’t have any car yet. – Prompt the user to enter all cars’ information (door, cylinder and width) until user enter EOF.

When the user enters EOF, the main function should stop reading and assign -1 to the remaining elements of all arrays. Note that the user should enter 3 values for each car. If the user enters successfully one or two values terminated by EOF for a car, the program should assign -1 to all elements of this car and stop the reading from the standard input.

– Display the sample output below by calling the following functions: M_PrintArray_04, M_Min_width_04, M_Count_cylinder_04 and M_DrawRectangle_04.
