div - compute the quotient and remainder of an integer division
div_t div(int numer, int denom);
The div() function shall compute the quotient and remainder of the division of the numera-
tor numer by the denominator denom. If the division is inexact, the resulting quotient is
the integer of lesser magnitude that is the nearest to the algebraic quotient. If the
result cannot be represented, the behavior is undefined; otherwise, quot* denom+ rem shall
The div() function shall return a structure of type div_t, comprising both the quotient
and the remainder. The structure includes the following members, in any order:
int quot; /* quotient */
int rem; /* remainder */
No errors are defined.
