Modding my code.

[Ralphus629]

I have this program that calculates and prints a cell phone bill. I've been stuck at how to approach this task. How would I update the program to prompt the user to enter the name of an input file (using a string type only) and the name of an output file that opens the files with the name.c_str() function? Any help would be greatly appreciated!
Thanks!

cin can read filename with the condition that this file name does not contain whitespace (since then it would read some of it). I guess this can be used to ask for input file and output file by the user.

name.c_str() returns a const char* null terminated c string. What do you want to do with it?

Basically im given an input file which has phone records of a cell phone bill program I previously wrote and take the user given records and output them to a user specified program in the same output format (or better)
