But C works on non-standard platforms. On a TI DSP I used this millennium, sizeof(char) == sizeof(short) == sizeof(int) == sizeof(float) == sizeof(double) == sizeof(void *) == 1. Each and every type was 32-bit. Each memory address pointed to a unique 32-bits, ie: (int *)0, and (int *)1 did not overlap on that system. As sizeof measures addressable units, not bytes, so they're all size 1. Even on more standard systems, int is 4 bytes on systems using an ILP32 or LP64 convention, but ILP64 is a thing too, making int 8 bytes.
