How to convert object to int?

Question

I have a class named object that have some instance vars. I want to save it to file. How can I cast it to type(eg int) that can be written to file?

Answer 1

If I understand correcty you want to save an object to hard drive? That is called serialization. You might want to check the boost library for that.

Answer 2

If it has several data members - you cannot do this (without using some external (3rd party) lib - that's an addition). Instead, write your own function for storing your object into a file, and one for reading from it.
