# Arithmetic Mean in c++?

C++Server Side ProgrammingProgramming

The Arithmetic Mean is just the average of numbers. In this program we will see how we can find the arithmetic mean from a set of numbers. The function will take the number set, and the number of elements. Out task is just adding each element, then divide it by number of elements that are passed.

## Algorithm

### arithmeticMean(dataset, n)

begin
sum := 0
for each element e from dataset, do
sum := sum + e
done
return sum/n
end

## Example

Live Demo

#include<iostream>
using namespace std;
float arithmetic_mean(float data[], int size) {
float sum = 0;
for(int i = 0; i<size; i++) {
sum += data[i];
}
return sum/size;
}
main() {
float data_set[] = {25.3, 45.21, 78.56, 96.21, 22.12, 36.97};
cout << "Mean: " << arithmetic_mean(data_set, 6);
}

## Output

Mean: 50.7283
