Watched a course by C++ on Coursera and there they said that you can connect the CSTDLIB library and use type data types: int16_t, uint16_t, int64_t, uint64_t , etc. Recently I learned that in the pros and how to write just Short Int, Long int , etc.
Question Actually is that there is the difference between them or is this one and the same?
Answer 1, Authority 100%
depending on the compiler and the system that you compile, the size of the built-in types (short , int , long , etc. ., In contrast, intxx_t , uintxx_t ) may differ.
In the standard (or somewhere else) you can read, in what limits the dimensions of these types may vary, but in practice, usually Short – 2 bytes, int – 4 , long – 4 or 8, Long Long – 8.
And intxx_t and uintxx_t , obviously, the size is always the same.
Answer 2, Authority 44%
short int and Long int – standard language types of dimensions of at least 16 and at least 32, respectively.
int16_t and int32_t – optionally supported aliases of types from the standard dimension library exactly 16 and exactly 32, respectively.
By the way, char8_t , char16_t and char32_t belong to the first type (i.e., keywords for non-fixed size), despite the name .
