write a program that reads data from a file whose name is given by the user and then outputs to another file called myoutput.txt. the input file contains 10 numbers-the output file will contain data on each of the 10 numbers broken up into the following categories:

A of how many numbers are positive

A listing of all the numbers

A count of how many numbers are negative

A sum of all the positive numbers

A sum of all the negative numbers

i kinda have an idea of how to do this but i can't figure out how to compute the sum once i determine if the number is negative or positive and how to save that to the output file.

please help !!!
