reading multiple txt file lines
I know i saw how to do this somewhere on the forums, but it seems to have dissappeared and i'm lost as how to do it. So, i will post this:
How do I write multiple lines to a text file, and then have my program read them/store them as variables? I have tried to do it with an array to no avail and i cant seem to find how to do this.
i want to store the information as strings and write them to a text file, and then get the them from the text file as strings. Also, how to write/read multiple lines of numbers would help me out as well.

Dynamic sized array to store strings: http://cplusplus.com/reference/stl/vector/
Get data from a file until '\n' is found: http://cplusplus.com/reference/iostream/istream/getline/
How to know when to stop reading from the file: http://cplusplus.com/reference/iostream/ios/good/
How to write data into file: http://cplusplus.com/reference/iostream/ostream/operator%3C%3C/
Useful: http://cplusplus.com/doc/tutorial/files/
Not sure how you want to load the numbers, individually or as strings?

well, i just want it to write values to a file and then grab those values for use as variables, or to show a list made using the program.
EX: I made a list program that stores strings in a file, but it asks for input and directly stores them into the file instead of useing an array or somthing like that. Instead of opening the text file to see your list, i want the program to display them for you.
EX2: If i have a check book, same thing as example 1, store and show, etc.
