C int byte size
WebWe are also using sizeof () operator to get size of various data types. When the above code is compiled and executed, it produces the following result which can vary from machine to machine − Size of char : 1 Size of int : 4 Size of short int : 2 Size of long int : 4 Size of float : 4 Size of double : 8 Size of wchar_t : 4 WebIn the table mentioned above, the integer is 16-bit or 2 bytes wide. Thus, the compiler is also 16-bit or 2 bytes wide. If the compiler was 32-bit wide, the int type size would have …

WebJan 5, 2011 · The standards do not specify the size in bytes, because the definition of the byte is up to the implementation, e.g. char is byte, but byte size ( CHAR_BIT macro) may be 16 bit. The actual size as defined by the implementation. This, as other answers have already pointed out, is dependent on the implementation: the compiler. WebFeb 12, 2014 · The size of an int is really compiler dependent. Back in the day, when processors were 16 bit, an int was 2 bytes.
