Char str1[] = "I was here";
Char* str2 = "I was here";
Int16 size1 = sizeof("I was here");
Int16 size2 = strlen ("I was here");
Int16 size3 = sizeof (str1);
Int16 size4 = sizeof (str2);
Char msg[100];
StrPrintF (msg,
"size = %d, size2 = %d, size3 = %d, size4 = %d\n",
size1, size2, size3, size4);
DbgMessage (msg);
You should see 11, 10, 11, 4 output.
A string literal is always counted as the amount of space required. Hence
the str[] and sizeof("...") will be the same, which is StrLen("...") + 1.
Only if the variable is a Char* will it be 4, since the compiler has no way
of knowing the contents of what it might be pointing at.
