Webb30 juli 2013 · For example, on 32 bits architecture the size of an address is 4 bytes : sizeof (void *) == 4 Bytes. sizeof (void *) == 8 bytes. Note, that all pointers have the same size interdependently of the type. So if you execute your code, the size of a int16 pointer and the size of int32 pointer will be the same.

WebbIn above table, the integer is 2 byte (or 16-bit) wide and hence compiler is also 2 byte or 16-bit wide. Had been the compiler 32-bit wide, the size of int type would have been 4 bytes (32-bits). However, this might not be the case every time. It is possible that size of integer is 4 byte (32-bits) for 64-bit processor. It’s all compiler dependent.
