Help, C++ Question

Given an integer, n, the integers a and b are said to be factors (or divisors) of n if a*b = n.

Given an integer, n, that is greater than 0,

n is an abundant number if the sum of its factors is greater than 2* n

n is a deficient number if the sum of its factors is less than 2* n

n is a perfect number if the sum of its factors is equal to 2* n

Design and implement a complete C++ program that will

read a series of integers from a file (via Linux redirection) and display (to the screen) a table with 4 columns (n, abundant, deficient, perfect)

for each integer read from the file, display

o the integer

o an 'X' or a blank in the appropriate column of the table (note: if the integer does not fall into any of the 3 categories, leave all columns blank)

when all data has been read and processed, display the average of the abundant numbers with a label and 2 digits to the right of the decimal

NOTES:

Assume that all input values in the data file will be integers (positive, negative, or zero).

Right justify the numbers and 'X's in the table. Assume maximum number of columns needed to display a number is 12.

When constructing data files, separate each integer with whitespace. Each line in the data file should be terminated with a linefeed.
