Please Explain this code: #include #include using namespace std; int main() { int size = 100; double arr[size]; for (int i = 0; i < size; i++) { arr[i] = i; } double meanOfElements = 0; for (int i = 0; i < size; i++) { meanOfElements += arr[i]; } meanOfElements /= size; double standardDeviationOfElements = 0; for (int i = 0; i < size; i++) { standardDeviationOfElements += (arr[i] - meanOfElements) * (arr[i] - meanOfElements); } standardDeviationOfElements = sqrt(standardDeviationOfElements); cout << "Mean: " << meanOfElements << " " << "Standard Deviation: " << standardDeviationOfElements << '\n'; return 0; }
Please Explain this code:
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
int size = 100;
double arr[size];
for (int i = 0; i < size; i++)
{
arr[i] = i;
}
double meanOfElements = 0;
for (int i = 0; i < size; i++)
{
meanOfElements += arr[i];
}
meanOfElements /= size;
double standardDeviationOfElements = 0;
for (int i = 0; i < size; i++)
{
standardDeviationOfElements += (arr[i] - meanOfElements) * (arr[i] - meanOfElements);
}
standardDeviationOfElements = sqrt(standardDeviationOfElements);
cout << "Mean: " << meanOfElements << " "
<< "Standard Deviation: " << standardDeviationOfElements << '\n';
return 0;
}
