Prototype

div_t div(int numer, int denom);

Description

Divides two integers, returning quotient and remainder.

div divides two integers and returns both the quotient and the remainder as a div_t type. numer and denom are the numerator and denominator, respectively. The div_t type is a structure of integers defined (with typedef) in stdlib.h as follows:

typedef struct {

int quot; /* quotient */

int rem; /* remainder */

} div_t;

Return Value

div returns a structure whose elements are quot (the quotient) and rem (the remainder).

Example

 /* div example */
 #include <stdlib.h>
 #include <stdio.h>
 div_t x;
 int main(void)
 {
    x = div(10,3);
    printf("10 div 3 = %d remainder %d\n",
    x.quot, x.rem);
    return 0;
 }
