what is the code suppose to do?

Answer 2

it reads in name and number from keyboard. so name, number, name, number. and than will calculate averages after the instances are created. in the constructor a map is build so u can later access the different instances. but somewhere there it is going wrong. although the error part can not be hughly wrong. for example: delete the last for loop in the program and it will compile and execute.
