| Half of the C standard refers to the language itself, which includes specific guarantees about what types are available, what syntax you can use, et cetera. These guarantees are sometimes too broad to work with comfortably. For example, in standard C, it is guaranteed that at least the following types exist: | Half of the C standard refers to the language itself, which includes specific guarantees about what types are available, what syntax you can use, et cetera.

| Each type in the list must be wider than the last, but there is a lot of leeway for systems to choose different sizes. For example, on a DSP or an old supercomputer all of the types might be exactly the same size. There is also no guarantee that a byte has 8 bits (maybe it has more than 8 bits). | Each type in the list must be wider than the last, but there is a lot of leeway for systems to choose different sizes.
