In most cases where you use sizeof, you're using it to find the width of a variable, not a datatype. Unfortunately code like this is still quite common: short ara[10]; memset(ara, 42, sizeof(short)); But what happens if we change ara's datatype, but forget to fix the code properly? long ara[10]; memset(ara, 42, sizeof(short)); So we should use this instead: long ara[10]; memset(ara, 42, sizeof ara); Regards Andrew
