Im having a bit of trouble reading CSVs. I have multiple types of data, so i am not sur开发者_如何转开发e how to get this to work:

string, string, bool, bool, int

I cant simply use >> to read in the data since the deliminator is not whitespace. scanf doesnt work, since it needs a human input, not file input, getline only reads in strings and also includes the \n char for some reason.

how can i read my csv properly?


You CAN use getline. There's an overload where the third argument passed can be a char for the delimiter. Just throw it all in a loop


Another option (which isn't typically recommended for C++, though), is fscanf. You're right that scanf is no good for you, but fscanf is its file-based equivalent.

Another canonical solution typically employed in C, but which isn't so strongly recommended in C++, is to go ahead and use getline, and then use strtok or a simple parser to parse each line.
