Assignment 2 uses structured design implemented in C

Assignment 2 uses structured design implemented in C. Array of records (structs) with file I/O is needed. The program takes two inputs at a time. The name of a person, and, the coin value as an integer in the range 5 to 95. Input coin values should always be divisible by 5 (integer division). Names are one word strings. An example input is: Jane 30 This input line indicates that 30 cents change is to be given to Jane. Output change values need to be in multiples of 50, 20, 10 and 5 cents. The program should aim to give as much of the higher valued coins as possible. A poor solution for an input of 30 cents is to give six 5 cent coins. A better solution is to give a 20 cent coin and a 10 cent coin. Input to the program comes from a data file called coins.txt . There can be 0 and up to 10 input lines like the example above. It is also possible to have the same name repeated in the data file but the coin values can be different. When the name is the same, it would mean the same individual. If the name is the same, your program would need to add up the coin amounts to obtain a total amount for that individual before computing the change to be given. Once your program has read in the data from coins.txt , your program will close coins.txt first, and then show a console screen menu as illustrated below. The program will continue to show the menu and execute the menu options until “Exit” is selected by entering the value 2 at the menu prompt. 1. Enter name 2. Exit When the user enters the value 1 at the menu prompt, your program will ask for a name. As an example, if the user enters the name Jane, the program will output: Customer: Jane 30 cents Change: 20 cents: 1 10 cents: 1 Change values of 0 are not shown. If the user enters a non-existent name (e.g. Donald) at menu option 1, and therefore would not be in the array of records, your program will print: Name: Donald Not found After the process output for menu option 1, the menu is redisplayed. If the user enters 2 to exit, your program will write the coin and change data in CSV format to file called change.csv . After writing the data to the file your program will exit. In change.csv , the data line for Jane will look like the following, with each value separated by a comma and the line is terminated by newline: Jane,30,0,1,1,0 Each data line in change.csv will be in the format: name of person,total coin value , number of 50 cent coins , number of 20 cent coins,number of 10 cent coins,number of 5 cent coins newline . So in the example output, Jane has 30 cents in one 20 cent coin and one 10 cent coin. There are no 50 or 5 cent coins. The output data file change.csv cannot have repeated names. You need to provide a test plan to fully test your algorithm and program, and provide an input data file, coins.txt , that contains test data in the specified format for testing your program. Your solution (program and algorithm) should be modular in nature. Use a high cohesion and low coupling design. Your solution (program and algorithm) should be modular in nature. This requires the submission of a structure chart and a high-level algorithm and suitable decompositions of each step.
