What??? I find it difficult to believe this is a subject for argument!
A string constant is a character ARRAY and therefore sizeof returns the
storage taken by the string constant. If you have an array: int foo[10][10],
sizeof(foo) will return 100 * sizeof(int) despite the fact that foo is a
pointer. If you don't believe me just run the following program on your
MAINFRAME yourself.
#include <stdio.h>
main()
{
printf("sizeof(\"abcdef\") = %d\n", sizeof("abcdef"));
}
This will return 7.
