You have been given $8$ C files, each has the same logic, expressed in different ways. Each of the files is incomplete, marked by TBD$.$ You must replace each TBD entry with appropriate C code. You must NOT alter any of the existing lines. You are only allowed to replace each TBD line with new lines.

Each of the C programs do exactly the same task. Given a list of numbers on the command line, they find the sum, sum of squares and the sum of cubes. You do not have to add error checking. You can safely assume that all numbers are given nicely as integers on the command line and are in the range of $-100$ to $100.$
