hi! i'm very new to c++, but i have some prior experience with python and java. in my computer science class, we have learned the basics of c++ up until for loops and while loops, in addition to how to create a text file. we use online gdb for our class because visual studio isn't working on the computers.
today, we were given an assignment where we have to create a program that encrypts and decrypts a given text file. i'm not sure if we have learned enough to complete this task, so i wanted to ask what topics i should look over when encrypting and decrypting text files.
