Problem solving and debugging.
Linux redirection to read data from a file.
Use of count-controlled loop.
Nested loop.
An abundant number is an integer greater than 0 such that the sum of its proper divisors is greater than the integer. For example, 12 is abundant because 1+2+3+4+6 = 16 which is greater than 12.
A deficient number is an integer greater than 0 such that the sum of its proper divisors is less than the integer. For example, 8 is deficient because 1+2+4 = 7 which is less than 8.
A perfect number is an integer greater than 0 such that the sum of its proper divisors is equal to the integer. For example, 6 is perfect because 1+2+3 = 6.
Data File Description
A data file for this exercise will consist of several integers separated by whitespace. The first integer in the file will be greater than 0 and will indicate how many data values are to be processed.
Here are 2 sample data files:
3
17 -5 246
8 0 11 -12354 894
183 -67 14 33333
Design and implement a complete C++ program that using Linux redirection, reads the first integer in the file to determine how many data values to process for each of the data values, determines if the integer is abundant, deficient, perfect or neither and displays a message that includes the integer and which of the 4 categories it falls into if the integer is abundant, counts how many factors it has and displays a message that includes its factor count
