Fundamentals of Programming II Spring 2017 Homework 2 10 points
Write a program in a file named change.cpp that will read a series of positive integers each representing a number of cents from a file. For each integer, the program will compute the minimum number dollars, quarters, dimes, and pennies that would be needed to give out the amount in change. (Do not use nickels.) These results are to be output to a file in tabular format as shown below with each field having a width of 10. The program must be implemented using a function compute_change that receives a positive integer representing a number of cents and passes back the number of dollars, quarters, dimes, and pennies. A function prototype must be written above the main program and the function definition must be written below the main program. Here are some notes that may be helpful. • The change should be computed from dollars to pennies, i.e. largest to smallest. • The change for each denomination can be computed using integer divide and remainder (%). • Value parameters are copies of the actual argument, so they can be used like local variables. The program must accept the input and output file names as commandline arguments. Proper error checking of the number of commandline arguments and successful file opens must be made. If the input file is named input.dat and contains the following data: 186 247 63 Then the program would be compiled and run using: $ clang++ change.cpp Wall o change $ ./change input.dat output.dat And the output file named output.dat should contain the following results: Amount Dollars Quarters Dimes Pennies 186 1 3 1 1 247 2 1 2 2 63 0 2 1 3
