I need help explaining this code, ESPECIALLY the median part of this code. So if you can just reference some important things to know about the code, key concepts, etc. and explain how the median part works it would be really helpful, thank you.

#include<iostream>
#include<cmath>

using namespace std;



int main()
{
const int size=56;
double R[size]={45.3, 67.8, 34.3, 51.2, 48.5, 61.3, 59.3, 65.1,
49.3, 42.4, 63.5, 69.8, 71.2, 39.8, 55.5, 53.2,
56.7, 48.8, 61.5, 51.2, 58.9, 63.1, 67.5, 62.4,
52.4, 50.2, 49.8, 56.8, 59.7, 60.4, 45.8, 43.8,
51.3, 54.8, 55.1, 52.3, 56.2, 59.7, 63.0, 46.7,
63.1, 58.2, 41.9, 59.2, 57.2, 67.3, 68.2, 38.9,
51.3, 63.8, 53.4, 58.9, 56.3, 58.9, 53.2, 56.8};

double min, max, range, sum, mean, std, variance , median;

sum =0;
min = R[0];
max = R[0];

// Find average
for(int count=0; count < size; count++)
{
sum=sum+R[count];
//Find Maximum
if (R[count]> max)
{
max=R[count];
}
//Find Minimum
if (R[count]< min)
{
min=R[count];
}
}
mean=sum/size;
range=max -min;

// Find the variance and standard devisation
double sum1 =0;
for (int i=0; i<=size-1; i++)
{
sum1=sum1+(R[i] - mean)* (R[i] - mean);
}
variance= sum1 / size;
std=sqrt(variance);

// Find the Median
for (int i=0; i< size -1; i++)
for (int j=i+1; j< size; j++)
{
if ( R[i] > R[j] )
{
//swap R[i] and R[j]
double temp = R[i];
R[i] = R[j];
R[j] = temp;
}
}

if ( size % 2 == 0 )
{
median = (R[size/2] + R[size/2 -1]) / 2;
}
else median = R[size/2];


cout << "Maximum = " << max << endl;
cout << "Minimum = " << min << endl;
cout << "Range = " << range << endl;
cout << "Mean = " << mean << endl;
cout << "Standard deviation = " << std << endl;
cout << "Variance = " << variance << endl;
cout << "Median = " << median << endl;
return 0;
}
