PLEASE HELP C++

Write a program in C++ that reads in a text file of test scores and prints out a histogram of the scores. The file format is as follows: the first line of the file contains a single positive integer, n, representing the number of test scores. Each of these test scores will be non-negative integer less than or equal to 100. The histogram should have one row on it for each distinct test score in the file, followed by one star for each test score of that value. For example, if the tests scores in the file were 55, 80, 80, 95, 95, 95, and 98, the output to the screen should look like

55*

80**

95***

98*
