Write a program that asks the students to enter the number of courses they each have and then, store it a vector. The program should contain a function, findMedian(...) that accepts as arguments a vector containing the number of courses. The function returns the median value of the number of courses to the main(). The program has additional requirements as follows: ▪ The program should ask number of users as input to decide the size of the vector. ▪ Do not use the '[ l'operator to access the elements of the vector. ▪ Use pass-by-reference to pass the vector to the function findMedian(...). MEDIAN: a set of values 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. Example output: Case 1: odd number of elements in the vector 5 2145 The median is: 4 Example output: Case 2: even number of elements in the vector 3425 The median is: 3.5

Is it preferable to use fully qualified references or unqualified references when referencing a subprogram, variable, or object in code? Issues with C's primitive encapsulation and how they manifest in C++ are discussed.

Analyze and write a comparison of using C++ pointers and Java reference variables to refer to fixed heap-dynamic variables. Use safety and convenience as the primary considerations in the comparison.

In programming, is it preferable to use unqualified references to subprograms, variables, and objects or fully qualified ones? Issues with C's primitive encapsulation and how they manifest in C++ are discussed.
