WebJan 17, 2011 · short usually leads to the same or worse performance than int (assuming sizeof (short) < sizeof (int) ). Performance degradation happens when you assign a result of an arithmetic operation (which is usually int, never short) to a variable of type short, which is stored in the processor's register (which is also of type int ). WebApr 10, 2024 · Besides the minimal bit counts, the C++ Standard guarantees that 1 == sizeof (char) ≤ sizeof (short) ≤ sizeof (int) ≤ sizeof (long) ≤ sizeof (long long).. Note: this allows the extreme case in which bytes are sized 64 bits, all types (including char) are 64 bits wide, and sizeof returns 1 for every type. [] Floating-point type[] Standard floating …
WebSep 24, 2006 · The most common use of short is when you know you may have a large numbers of them (a short array will obviously take half the space of an int array). And a bit of history: in the old days of DOS and 16 bit CPUs int were 16 bit. One of the result of this was that you could "see" this limit as an user of an application.

WebSep 9, 2024 · The data types in C can be classified as follows: Types. Description. Primitive Data Types. Arithmetic types can be further classified into integer and floating data types. Void Types. The data type has no value or operator and it does not provide a result to its caller. But void comes under Primitive data types.
