Code has to be in C++

In statistics, when a set of values is sorted in ascending or descending order, its median is the middle value. If the set contains an even number of values, the median is the mean, or average, of the two middle values. Write a function that accepts as arguments a vector of integers (use pass by reference). The function should determine the median of the vector elements and return the value to the main(. Check your output for both, even and odd number of vector elements
