Question

Create a program to be used in a coin sorting machine. The machine takes U.S. pennies, nickels, dimes, and quarters. The base specifications for these are as follows: nickel dime quarter penny diameter 19.05 mm 21.21 mm 17.91 mm 24.26 mm weight 2.5 g 5.0 g 2.268 g 5.670 g The machine is equipped with sensors that measure the diameter and weight of each coin in order to identify and count each type of coin. Since coins can be subject to wear and tear, each coin diameter and width is allowed a tolerance: +-2%. Your program must: a) declare constants for all constant values (base diameters, base widths, tolerance percentage) b) calculate and store the acceptable high and lowvalues for each coin for diameter and width c) at the start, output the acceptable high and low values d) open and read coin data from the given data file and classify the coin based on the coin data, which is stored as a diameter and a weight, one coin on a line (partial file shown here) 17.7084 2.27567 18.2629 2.28056 18.0828 2.27956 19.4268 2.46291 19.4004 2.5018 21.3491 5.01808 17.6017 2.22427 21.2601 4.9028 18.7941 2.46094 23.7941 5.67778 21.4238 4.93848 17.8968 2.268 e) store the number of coins of each type as each is classified f) output the number and value of valid coins and the number of invalid coins, sample output shown below

Here is the code for you:

    if(coinDia >= acceptable_coin_diameter_low && coinDia <= acceptable_coin_diameter_high && coinWeight >= acceptable_coin_weight_low && coinWeight <= acceptable_coin_weight_high)
        return true;
    return false;
