Save file troubles - c++

Question

Ok. I'm trying to finish writing to a file and then reading from a file but I keep getting an error when I start the void readData(void).The error is "no matching token found." What could I do to make this work/ make it easier?
I'm not understanding how to use the void function, I think. I'm sure there are more issues because when I remove void readData(void) the error moves to void writeData(void).
