Websize_t can store the maximum size of a theoretically possible object of any type (including array). size_t is commonly used for array indexing and loop counting. Programs that use other types, such as unsigned int, for array indexing may fail on, e.g. 64-bit systems when the index exceeds UINT_MAX or if it relies on 32-bit modular arithmetic.

WebAug 9, 2024 · To help address the above downsides, C++ also defines two alternative sets of integers that are guaranteed to be defined. The fast types (std::int_fast#_t and std::uint_fast#_t) provide the fastest signed/unsigned integer type with a width of at least # bits (where # = 8, 16, 32, or 64). For example, std::int_fast32_t will give you the fastest ... WebAug 9, 2024 · That is, for 32-bit applications, std::size_t will typically be a 32-bit unsigned integer, and for a 64-bit application, size_t will typically be a 64-bit unsigned integer. …

WebDec 16, 2014 · Yes, this code assumes that (sizeof (size_t) >= sizeof (int)). I suppose there could be a platform where that test fails, but I do not know of one. For those who, like me, don't know ssize_t is guaranteed to hold values from at least -1 to SIZE_MAX. So casting val to ssize_t gets rid of the unsigned-ness.

WebMar 10, 2011 · In Win32, size_t is defined as unsigned int, unsigned int and size_t are all 4 bytes long. In X64, unsigned int is a 32 bit type and size_t is a 64 bit type.
