Paper for above instructions
In programming, especially when dealing with numerical data and arrays, it's crucial to implement functions that are modular and reusable. This assignment requires us to create a C++ program to calculate and display three things: the total amount won, the average winnings, and the day on which the highest amount was won. Each of these computations will be performed using separate functions for a cleaner and more organized code structure.
Code Explanation
1. Overview
The program starts by declaring an array to hold the winnings for five days. The total amount of winnings, average amount won, and the day with the highest winnings will be calculated using modular functions.
2. Modifying the Existing Program
To enhance the given partial code, we will implement three functions: `getTotal()`, `getAvg()`, and `getHighDay()`. Here’s how:
1. `getTotal()`: This function calculates the total winnings by iterating over the winnings array and summing the amounts.
2. `getAvg()`: This function computes the average by calling `getTotal()` to obtain the total winnings and dividing it by the number of days.
3. `getHighDay()`: This function identifies the day with the highest winnings by searching through the winnings array for the maximum value.
Implementation Steps
Below is the complete code with functions implemented:
```cpp
// Intermediate23.cpp
// Displays the total amount won, the average amount won, and
// the day number of the highest amount won
// Created/revised by
#include
#include
using namespace std;
// Function prototypes
int getTotal(int winnings[], int size);
double getAvg(int winnings[], int size, int total);
int getHighDay(int winnings[], int size);
int main() {
const int SIZE = 5; // Number of days
int winnings[SIZE] = {12500, 9000, 2400, 15600, 5400};
// Declare variables to store results
int total = getTotal(winnings, SIZE);
double average = getAvg(winnings, SIZE, total);
int highDay = getHighDay(winnings, SIZE);
// Display the results
cout << fixed << setprecision(2);
cout << "Total amount won: $" << total << endl;
cout << "Average daily amount won: $" << average << endl;
cout << "The contestant's highest amount won was on day " << highDay + 1 << "." << endl;
return 0;
} // end of main function
// Function Definitions
// Function to calculate total
int getTotal(int winnings[], int size) {
int total = 0;
for (int i = 0; i < size; i++) {
total += winnings[i];
}
return total;
} // end of getTotal function
// Function to calculate average
double getAvg(int winnings[], int size, int total) {
return static_cast
} // end of getAvg function
// Function to find highest day
int getHighDay(int winnings[], int size) {
int highAmount = winnings[0];
int day = 0;
for (int i = 1; i < size; i++) {
if (winnings[i] > highAmount) {
highAmount = winnings[i];
day = i;
}
}
return day; // return the index of the highest day
} // end of getHighDay function
```
3. Explanation of the Functions
- getTotal: This function takes an array of winnings and its size as parameters. It initializes a total variable and iterates through the array, adding each element to the total. The function returns the total value computed.
- getAvg: This function computes the average amount won by dividing the total (passed as a parameter) by the number of days (size). The return type is double to accommodate potential decimal values.
- getHighDay: This function goes through the winnings to find the maximum value and its corresponding index. The index is returned to denote the day on which the highest winnings occurred.
4. Output
Upon running this program, you will see outputs similar to:
```
Total amount won: 500.00
Average daily amount won: 00.00
The contestant's highest amount won was on day 4.
```
Conclusion
The breakdown of this program into distinct functions not only adheres to best practices in programming by promoting code reusability but also enhances readability and debugging. Each function serves a clear have a defined purpose; namely to compute the total, average, and identify the day with the highest winnings, thereby improving the maintainability of the code.
