Assignment Summary

In this assignment, you will create a program in C++ that will (hypothetically) be a software component of an electronic coin counting machine that counts American coins. Valid coin denominations are the integers 1, 5, 10, 25, and 50. The program shall count the number of coins (by denomination) that are read from a coin file that is submitted to the program by way of standard input (which by default is the keyboard). It shall then produce a formatted coin report printed on standard output (which by default is the computer screen). The report shall contain information that follows the wording and format shown in the example-program-execution.txt file.

Note that the program shall have no interaction with a user except for starting the program on the command line from within a command prompt window and redirecting the input file. This means that the program shall NOT prompt the user for the entry of any data.

Below is an example start of the program.

Smith11.exe < big-coin-file.txt

Format of a Coin File

The input data in a coin file shall consist of zero or more coin values, separated by spaces, tabs, or return characters, and terminated by a single mandatory 999 sentinel value that marks the end of the list of coins. The program may assume that all coin values are positive one-to-two-digit integers in the range from 1 to 99 inclusive. If a non-denominational number in that range (such as 40 or 71) is read from the input file, then that coin shall be counted as an invalid coin. (The 999 sentinel value shall neither be counted as an invalid coin, nor as any coin at all.)

Software Design

int main(void)

Declare integer variables to individually store the penny count, nickel count, dime count, quarter count, half dollar count, and invalid coin count. When doing so, set each to the value of zero. Then call the countCoins function, passing the six required parameters that it expects. Then call the produceCoinReport function, passing the six required parameters that it expects.

void countCoins(int &pennyCount, int &nickelCount, int &dimeCount, int &quarterCount, int &halfDollarCount, int &invalidCount);

Declare an integer variable to store the value of a coin. Then read a coin value from standard input (i.e., cin) and store it in the coin variable. After doing that, start a "while" loop that loops as long as the coin value does not equal the SENTINEL, which marks the end of the data.

Inside the "while" loop, set up an "else if" control structure that counts the coins. It should do this by comparing the current coin value to 1, 5, 10, 25, and 50. As soon as a comparison is true, the program should increment the count for that coin and move on to reading the next coin. If no coin match is found, then the program should count the coin as invalid. The basic design of the "else if" control structure should look something like this:

if the coin is a penny increment the penny count else if the coin is a nickel increment the nickel count else if ... ... else increment the invalid coin count

When the "else if" control structure is finished, read the next coin value from standard input and store it in the coin variable. (This read statement should be INSIDE the while loop.)

void produceCoinReport(int pennyCount, int nickelCount, int dimeCount, int quarterCount, int halfDollarCount, int invalidCount);

Declare an integer variable to store the total coin count and a floating point variable to store the grand total monetary value of the coins. Add up all the coin counts and store the total. Use the coin count of each coin along with the monetary value of each coin to calculate the total monetary value of all the coins. Store that answer. Print the coin report in the format shown in the example-program-execution file. Be sure to set the precision to 2 before printing the floating point numbers in the report.
