Pupils' heights
The health visitor at a school is going to measure the heights of all pupils. For each class she makes a statistics giving the number of pupils of each height and the average height.

Make a C++ program that helps the health visitor making the statistics.

Example:
In a class with 20 pupils the heights of the individual pupils, in centimeters, are:
175, 167, 160, 164, 183, 187, 188, 179, 176, 175, 169, 175, 176, 178, 165, 160, 173, 165, 187, 178
The program should read in all the numbers and make a table like this: height number of pupils
160 2
164 1
165 2
167 1
... ...
... ...
188 1
average height 174.0
Maximum Number of Students lies between 173 and 179
