[問題] 一個關於K&R書中範例的疑問
大家好，我想問原文K&R The C Programming Language(2nd Edition)第98頁中
/* writelines: write output lines */
void writelines(char *lineptr[], int nlines)
{
int i;
for (i = 0; i < nlines; i++)
printf("%s\n", lineptr[i]);
}
Since lineptr is itself the name of an array, it can be treated as a pointer
in the same manner as in our earlier examples, and writelines can be written
instead as
/* writelines: write output lines */
void writelines(char *lineptr[], int nlines)
{
while (nlines-- > 0)
printf("%s\n", *lineptr++); /*Why it uses the * operator?*/
}
書中下面的範例是不是寫錯了?
