What is uint_fast32_t and why should it be used instead of the regular int and uint32_t?
...way. Some are easier to access than others. Easier means less-computation, more direct, which results in faster access. Now uint32_t is exactly 32-bit on all systems (if it exists), which might not be faster compared to the one which has, say, 64-bit. uint_fast32_t on the other hand at least 32 bi...
