1 ASSIGNMENT #1 SOLUTION Total: 50 marks Objective of Assignment: To write a simple C program to solve a problem using no decision or repetition instructions and no function calls. Scope: Assignment covers materials up until end of chapter 1 and parts of chapters 2 & 3. Other Things to learn from Assignment : How to use a text editor, compile and run a C program, how to create and print a Unix script file and how to use some Unix commands. Problem: 1. Quick Relief (QR) is a charity organization that has collected non-perishable goods like water, soap, cereal, clothing and others from people so that they could donate the goods to recent hurricane victims. A harmonized sales tax (HST) of 13% should be applied to the given cost of the items to obtain the actual cost. QR agency has filled three car trunks with goods for donation and your job is to write an algorithm and a program to compute (a) the total cost of goods in each of the three trunks with the HST, (b) the total cost of goods in all the three trunks with HST, (c) the total weight of goods in each of the three trunks, and (d) the total weight of goods in all the three trunks. We are told that: i. Trunk 1 contains the following four items: (1) 70 cases of bottled water and each case costs $3:99, (2) 60 cereal boxes costing $6.00 per box, (3) 200 T-shirts costing $12.00 each, and (4) 80 dozens of ivory soap costing $2:49 per dozen. ii. Trunk 2 contains four items: (1) 150 cases of bottled water and each case costs $2:50, (2) 130 cereal boxes costing $4:50 per box, (3) 250 T- shirts costing $15.00 each, and (4) 300 dozens of ivory soap costing $3:50 per dozen. iii. Trunk 3 contains four items: (1) 100 cases of bottled water and each case costs $4:00, (2) 210 cereal boxes costing $4:00 per box, (3) 180 T- shirts costing $10.00 each, and (4) 240 dozens of ivory soap costing $3:10 per dozen. iv. A case of bottled water weighs 150 lbs (pounds), a box of cereal weighs 5 lbs, a T shirt weighs 4 lbs and a dozen of ivory soap weighs 3 lbs. Assume that all products of the same kind have the same weights. For example, all cereal boxes have the same weight and all T-shirts have the same weight. Again, Write an algorithm and a program to compute the cost of goods in each of the three trunks, the cost of the goods in all the three trunks, the weight of the goods in each of the three trunks and the weight of the goods in all the three trunks. Hint: You can set up your program to ask for the input values of the cost of each unit of the 4 items in each trunk (e.g., costs of each unit of the four items in trunk 1 are: ), followed by the input values of the number of each of the 4 items in each trunk (e.g., numbers of each of the items in trunk 1 are: ), etc. Your algorithm and program should print values for the following:

2 Details of Goods sent by QR Charity Agency: Total cost of goods in Trunk 1 with HST is: $ Total cost of goods in Trunk 2 with HST is: $ Total cost of goods in Trunk 3 with HST is: $ Total cost of goods in the three trunks with HST is: $ Total weight of goods in Trunk 1 is: lbs Total weight of goods in Trunk 2 is: lbs Total weight of goods in Trunk 3 is: lbs Total weight of goods in the three trunks is: lbs End of processing!!! Steps for Creating Materials to Hand in for Marking: 1. Type your algorithm solution in a text file called your userid_asn1.txt. 2. Then, type the C program solution into a source file called your userid_asn1.c. 3. Compile your C program with cc userid_asn1.c. 4. Then, run (execute it with a.out). 5. When your program is running with no errors, then, create a script file called userid_script1.txt and hand in your script file for marking. Your script file should show your algorithm, your source program, the compilation of the program, the running of the program with the input and output data shown. To create a script file, at unix prompt, do the following: script userid_script1.txt cat userid_asn1.txt cat userid_asn1.c cc userid_asn1.c a.out [note here when prompted by the cpu, enter the input data from the keyboard as your program has asked to read it and the result will be displayed on the monitor and captured in the script file]. exit Marking Scheme : 1. Correct Algorithm solution (10 marks) 2. Program Solution (10marks) 3. Error free Compilation of Program (10 marks) 4. Correct Running of the Program with Correct Input/Output Data (10 marks) 5. Correct creation and handing in of Script File (10 marks) *** The solution containing the algorithm, the C program, the compilation and the execution of the program showing the input and results of the run as in the script file cezeife_script1.txt is shown below:
