Convert from int to int32

Question

I have a bunch of int's in my c++ code that I need to change to int32's. Same with my bool's. What header do I need to include in order to use int32's and bool32's. Also how do I declare these once I make them. Am I able to just replace the int's with int32's?

For example:

int x;

Becomes

int32 x;

I am getting lots of errors when I try to change from int to int32. Here's a few:

error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

error C2086: 'const int x' : redefinition

Answer 1

<cstdint>

If your compiler supports it, will get you int32_t, the C99 fixed width integer type.

Never heard of no bool32 and I can't imagine what kind of sense it would even make.

Yes, you can just replace int with your type so long as your type remains fundamental and/or has a default constructor/non-implicit constructor...depending on use.

Answer 2

On windows you should be able to use the built in type __int32. I've never hear of a 32 bit bool, but you can just use typedef for that one.
