I need help getting the running time values, please help. Code in C++

In this assignment we will implement three different algorithms and compare their performance for doing-the same job by real observations. We will also determine how well these algorithms actually perform compared to their theoretical performances. We will use simulated data (using random number generator). You can implement the code in C, C+, Java. You will implement three sorting algorithms: INSERTION-SORT, HEAP-SORT, and QUICKSORT. The implementation should follow exactly the algorithms (pseudocode) learned in class
