div會這樣做見

reference和示例：

/* div example */

#include

#include

int main ()

{

div_t divresult;

divresult = div (38,5);

printf ("38 div 5 => %d, remainder %d.\n", divresult.quot, divresult.rem);

return 0;

}

輸出：

38 div 5 => 7, remainder 3.

編輯：

C規(guī)范說：

7.20一般用途

The types declared are size_t and wchar_t (both described in 7.17),

div_t

which is a structure type that is the type of the value returned by the div function,

ldiv_t

which is a structure type that is the type of the value returned by the ldiv function, and

lldiv_t

which is a structure type that is the type of the value returned by the lldiv function.

…但是沒有說明div_t的定義是什么.
