Cross-platform primitive data types in C++

Question

Unlike Java or C#, primitive data types in C++ can vary in size depending on the platform. For example, int is not guaranteed to be a 32-bit integer. Various compi

Answer 1

Two things:

First, there is a header file called limits.h that gives lots of useful platform specific information. It will give max and min values for the int type for example. From that, you can deduce how big the int type is.

You can also use the sizeof operator at runtime for these purposes too.

I hope this helps . . .
