14,287,991 | Is there a 64 bit type that in every OS(32/64 bit) and for every compiler has a size of 64?
The same question is also for 32 bit type. (It should be int?)
*The origin of the question is* : I am implementing the system which has 2 kinds of instructions :
1. 32 bit
2. 64 bit
I want to write something like:

] | If you want your code to be truly portable, then you probably want to typedef your own type, and use for example
```
typedef int32_t instruction32bit;
typedef int64_t instruction64bit;
```
This will work MOST of the time, but if it doesn't for a particular system/compiler/whatever, you can add do something li... | Use `uint_least32_t` and `uint_least64_t`. The fixed-size types `uint32_t` and `uint64_t` will not exist on systems that don't have the exact sizes they describe. |
