There

char* strings;

How do I dynamically allocate enough data for strings and properly and copy it into memory?

Read a good C++ book . https://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list — Steephen, Sep 17 '17 at 00:07

Use std::string. It will handle the allocation for you.

Practicing a lab at the moment for char * specifically. Is there a difference? Sorry, I'm still learning slowly. – TheNubProgrammer Sep 17 '17 at 00:19

@Jamal Do you know of any methods that i could do to dynamically allocate data for a char* by counting each line in the text file? – TheNubProgrammer Sep 17 '17 at 00:43
@TheNubProgrammer: using `char*` is for C. In C++, you should be using `std::string` instead. Coupled with `std::ifstream`, `std::getline()` and `std::vector`, all of the file I/O and memory management would be done for you. If you are learning C++, learn C++ properly, not C. – Remy Lebeau Sep 17 '17 at 07:47
