Question

challenge activity 3.10.2: soda machine with enums. the following program reads a number from input to indicate the coin inserted into a soda machine. organize the lines of code to add 10 to totaldeposit if the input is a dime. otherwise, if the input is a nickel, add 5 to totaldeposit. ex if the input is 1, representing named value add_dime, then the output is: totaldeposit: 10 note: not all lines of code on the left will be used in the final solution. how to use this tool unused totaldeposit = totaldeposit + 10; totaldeposit + 10; else if (userinput == add_dime) { else { totaldeposit = totaldeposit + 5; totaldeposit + 5; } else if (userinput == add_nickel) { } main.cpp #include <iostream> using namespace std; int main() { enum acceptedcoins {add_quarter, add_dime, add_nickel}; int totaldeposit; int userinput; totaldeposit = 0; cin >> userinput; if (userinput == add_quarter) { totaldeposit = totaldeposit + 25; } else { cout << \invalid coin selection.\ << endl; } load default template...

Explanation:

Step1: Insert DIME condition block

else if (userInput == ADD_DIME) {
    totalDeposit = totalDeposit + 10;
}

Step2: Insert NICKEL condition block

else if (userInput == ADD_NICKEL) {
    totalDeposit = totalDeposit + 5;
}

Step3: Add output for totalDeposit

cout << "totalDeposit: " << totalDeposit << endl;

Answer:

The completed main.cpp code is:

#include <iostream>
using namespace std;

int main() {
    enum AcceptedCoins {ADD_QUARTER, ADD_DIME, ADD_NICKEL};
    int totalDeposit;
    int userInput;

    totalDeposit = 0;
    cin >> userInput;

    if (userInput == ADD_QUARTER) {
        totalDeposit = totalDeposit + 25;
    }
    else if (userInput == ADD_DIME) {
        totalDeposit = totalDeposit + 10;
    }
    else if (userInput == ADD_NICKEL) {
        totalDeposit = totalDeposit + 5;
    }
    else {
        cout << "Invalid coin selection." << endl;
    }
    cout << "totalDeposit: " << totalDeposit << endl;
    return 0;
}

When input is 1 (ADD_DIME), output is:
totalDeposit: 10
When input is 2 (ADD_NICKEL), output is:
totalDeposit: 5
When input is 0 (ADD_QUARTER), output is:
totalDeposit: 25
When input is invalid, output is:
Invalid coin selection.
totalDeposit: 0
