## How do I implement the mean1d function to find the mean in this code?

Code:
```#include <iostream>
using namespace std;

int main()
{

//I'll be making a 1 dimensional array
int array1d[25];

array1d[0] = 9;
array1d[1] = 8;
array1d[2] = 7;
array1d[3] = 5;
array1d[4] = 3;
array1d[5] = 7;
array1d[6] = 4;
array1d[7] = 7;
int array1d_size = 8;

cout << "The original array is: { ";
for (int i=0; i<array1d_size; i++)
cout << array1d[i] << " ";
cout << "} " << endl;

double the_mean = mean1d(array1d, array1d_size);
cout << "\n=====> The mean is: " << the_mean;

}```

What do you understand by "arithmetic mean"? From there, you should have an idea of how to implement it.
