I made this small and very simple to-do list project to remember how to work with C++. Reading files, types, and the standard libraries are a few things I was looking forward to reviewing. It's simple and a good restart after years without touching C++.
The idea was to recall some of the things learned in the past. Initially, the idea was to use only scanf, printf, and static arrays, most likely in C style. Later, this changed due to simplicity.
The change from char* to std::string came from the Stack Overflow page, which defined std::string as more suitable than char* (unless you are writing a DLL).
std::cin was easier to use than scanf (and I forgot how to read input dynamically).
printf is still in the project.
