Question
![This program tabulates scores for a figure skating competition that has four parts:
1. The short dance, which is worth 25% of the final score
2. The free skate, which is worth 50% of the final score
3. The partner dance, which is worth 10% of the final score
4. The original performance, which is worth 15% of the final score
The array `weights` stores values that represent how much of the final score each of the four parts is worth.
Complete this program to read in each of the four scores as `float` values, multiply each score by its corresponding weight, and then sum up the weighted scores to get the participant’s final score as a `float` value.
```cpp
#include <iostream>
#include <vector>
using namespace std;
const int WEIGHT_SIZE = 4;
int main() {
float weights[WEIGHT_SIZE] = {0.25, 0.50, 0.10, 0.15};
float total = 0.0;
// TODO: Write your code here
cout << "Final Score: " << total << endl;
}

Transcribed Image Text:# Understanding the Mode of a Dataset
## Definition
The **mode** of a dataset is the item that appears most frequently.
## Instructions
You are required to write a program to read in numbers between 1 and 100 and then report the mode. If more than one number appears most frequently, choose the highest number. The program's output should be in the following format:
```
The most frequent value was 42, appearing 9 times.
```
## Sample Code
Below is a snippet of C++ code with the basic structure to find the mode of the entered numbers.
```cpp
#include <iostream>
using namespace std;
int main() {
// TODO: Write your code here
cout << "The most frequent value was " << 50 << ", appearing " << 8 << " times." << endl;
}
```
### Explanation
- **Include Directives**: `#include <iostream>` is used to include the standard input-output stream library.
- **Namespace**: The `using namespace std;` line allows the program to use all the entities in the `std` namespace.
- **Main Function**: This is the entry point of the program.
- A comment indicates where the code to find the mode should be inserted.
- The `cout` statement is used to output the most frequent value found and how many times it appeared.

There is a visual representation (pictured as a handwriting scribble) beside the code. It might suggest a flow or thought process, but it appears to be non-informative or illustrative for technical purposes.
