Question

// SuperMarket.cpp - This program creates a report that lists weekly hours worked

// by employees of a supermarket. The report lists total hours for

// each day of one week.

// Input: Interactive

// Output: Report.

#include <iostream>

#include <string>

using namespace std;

int main()

{

// Declare variables.

const string HEAD1 = "WEEKLY HOURS WORKED";

const string DAY_FOOTER = " Day Total ";

// Leading spaces in DAY_FOOTER are intentional.

const string SENTINEL = "done"; // Named constant for sentinel value.

double hoursWorked = 0; // Current record hours.

string dayOfWeek; // Current record day of week.

double hoursTotal = 0; // Hours total for a day.

string prevDay = ""; // Previous day of week.

bool notDone = true; // loop control

// Print two blank lines.

cout << endl << endl;

// Print heading.

cout << "\t\t\t\t\t" << HEAD1 << endl;

// Print two blank lines.

cout << endl << endl;

// Read first record

cout << "Enter day of week or done to quit: ";

cin >> dayOfWeek;

if(dayOfWeek == SENTINEL)

notDone = false;

else

{

cout << "Enter hours worked: ";

cin >> hoursWorked;

prevDay = dayOfWeek;

}

while(notDone == true)

{

// Implement control break logic here

// Include work done in the dayChange() function

}

cout << "\t\t" << DAY_FOOTER << hoursTotal << endl;

return 0;

} // End of main()

**Accumulating Totals in Single-Level Control Break Programs**

In this section, we explore how to accumulate totals in Single-Level Control Break Programs using C++.

### Weekly Hours Worked

Here is a breakdown of hours worked by employees over a week:

- **Monday**: 6 hours (employee 1)
- **Tuesday**: 2 hours (employee 1), 3 hours (employee 2)
- **Wednesday**: 5 hours (employee 1), 3 hours (employee 2)
- **Thursday**: 6 hours (employee 1)
- **Friday**: 3 hours (employee 1), 5 hours (employee 2)
- **Saturday**: 7 hours (employee 1), 7 hours (employee 2), 7 hours (employee 3)
- **Sunday**: 0 hours

An example program execution is shown below, demonstrating how to input the days and hours worked for accumulation:

```
WEEKLY HOURS WORKED

Enter day of week or done to quit: Monday
Enter hours worked: 2
Monday 2

Enter a day of week or done to quit: Monday
Enter hours worked: 4
Monday 4

Enter a day of week or done to quit: Tuesday
Enter hours worked: 8
```

### Additional Notes

On the right side, there is a snippet of C++ code (SuperMarket.cpp) demonstrating variables and logic structures for processing data input. Important sections include:

- Declaring variables and using namespaces.
- Printing headers and formatting outputs.
- Reading and processing user inputs for day and hours worked.

This code snippet can be used as a base to understand control break logic, where records are processed until a certain condition is met (e.g., the user quits).

**Accumulating Totals in Single-Level Control Break Programs**

In this educational exercise, you'll explore how to accumulate totals using single-level control break programs with an example provided in C++. This practice will aid in understanding how such programs handle data input and processing.

### Weekly Hours Worked Example

The program helps users input and tabulate hours worked by employees over a week. Here’s a step-by-step breakdown of the sample execution:

1. **Saturday:**
- Employee 1: 7 hours
- Employee 2: 7 hours
- Employee 3: 7 hours

2. **Sunday:**
- 0 hours worked

### Example of Program Execution

The program simulates accumulating work hours as follows:

- **Input Sequence:**
- Day: Monday, Hours: 2
- Day: Monday, Hours: 4
- Day: Tuesday, Hours: 8

- **Output:**
- Total hours for Monday: 6
- Total hours for Tuesday: 8

**Sample Code Snippet:**

The right side displays a C++ code example guiding the user through coding such a program. This includes importing necessary libraries, declaring variables, and performing standard input-output operations.

### Grading

Upon completion of the program, users need to click the "Submit" button to record their score and progress.

This exercise provides insight into handling input-based loops and control break logic within C++ programming.
