I need help with this. Please provide comments for each section that way I can see what's going on. The more comments the better. Any help is appreciated.

Read in an integer (any valid 64-bit integer = long long type) and output the same number but with commas inserted. So if the user entered -1234567890 your program should output -1,234,567,890. Commas should appear after every three significant digits (provided more digits remain) starting from the decimal point and working left toward more significant digits. If the number entered does not require commas, do not add any. For example, if the input is 234 you should output 234. The input 0 should produce output 0. Note in the example above that the number can be positive or negative. Your output must maintain the case of the input.

This problem could be easily solved if you were allowed to read the information in as a string or character by character. However, the input will be read in as a single integer and you will need to use appropriate arithmetic to isolate and print each digit of the number one at a time and output commas at appropriate locations.
