### div -- Calculate Quotient and Remainder

Format

>     #include <stdlib.h>
>     div_t div(int numerator, int denominator);

Language Level: ANSI, POSIX, XPG4
div calculates the quotient and remainder of the division of numerator by denominator.

Return Value
div returns a structure of type div_t, containing both the quotient int quot and the remainder int rem. If the return value cannot be represented, its value is undefined. If denominator is 0, an exception will be raised.

Example
This example uses div to calculate the quotients and remainders for a set of two dividends and two divisors.

    #include <stdlib.h>
    #include <stdio.h>

    int main(void)
    {
       int num[2] = {45,-45);
       int den[2] = {7,-7);
       div_t ans;   /* div_t is a struct type containing two ints:
                       'quot' stores quotient; 'rem' stores remainder */
       short i,j;

       printf("Results of division:\n");
       for (i = 0; i < 2; i++)
          for (j = 0; j < 2; j++)
          {
             ans = div(num[i],den[j]);
             printf("Dividend: %6ld  Divisor: %6ld", num[i], den[j]);
             printf("  Quotient: %6ld  Remainder: %6ld\n", ans.quot, ans.rem);
          }
       return 0;

       /*****************************************************************
          The output should be:

          Results of division:

          Dividend: 45  Divisor:-7  Quotient:-6  Remainder: 3
          Dividend:-45  Divisor: 7  Quotient:-6  Remainder:-3
