Langauge C++ Write three functions that each generate 10 unique dataset files of integers separated by a comma ",". E.g., 34, 32421, 124124, 67, 92, ... The sizes of these 10 datasets are (n) 1000, 4000, 8000, 10000, 40000, 80000, 100000, 400000, 800000, 1000000. One function should generate random integers between 0 to 1,000,000 as the elements of each dataset. Another function should generate a file with a sorted list of integers from smallest to largest. The final function should generate a file with a reverse sorted list with values going from largest to smallest. E.g., 1000Sorted file will have 0 to 999, 1000Reverse.txt will have 999 to 0, and 1000Random.txt will have random numbers between 0 to 1,000,000. These functions should not take any input arguments and should have the signature: void GenerateSortedInputFiles(), void GenerateRandomInputFiles(). void GenerateReverseInputFiles(). The output of these functions is just a print statement to console that file generation completed. The files names should have the format SampleSize + Random/Sorted/Reverse + .txt eg. 80000Sorted.txt.
