In the end please specify which types of sorting algorithms was used and why. Thank you

Using one of the following sorting algorithms types : Insertion sort or Selection sort Help making a C++ program which demonstrates the application of the chosen sorting algorithm above in solving a real-world problem for sorting game score or sorting students marks and grades. The coding should compulsarily consist 2 files. a) Header file (Sort.h) b) Main file (SortMain.cpp) At last, please do explain of how the basic algorithm works including the efficiency of the algorithm in detail. Thank you
