如何求了出数组元素个数，这个问题好像有人提过，不过好像没完。


我在这儿再提一小下。

同意zoukh(无名) ：
这是最通用的算法。

[prototype]

char a[100];

int sizeofa = sizeof(a) /sizeof char;

is it ok?

[earthharp]

sizeof (array)/sizeof(type of element)

[zoukh]

TYPE rg[BOUNDS};

size_t cbrg = sizeof(rg)/sizeof(rg[0]);

But inside
void foo(int rg[])
you can't do that since array to pointer conversion is already done and rg is just a pointer.
