Computes the quotient and the remainder of two integer values.
#include <stdlib.h>
div_t div( int numer, int denom );
| numer | Numerator | |
| denom | Denominator |
The div function divides numer by denom, computing the quotient and the remainder. The div_t structure contains the following elements:
| Element | Description |
| int quot | Quotient |
| int rem | Remainder |
The sign of the quotient is the same as that of the mathematical quotient. Its absolute value is the largest integer that is less than the absolute value of the mathematical quotient. If the denominator is 0, the program will terminate with an error message.
The div function returns a structure of type div_t, comprising both the quotient and the remainder. The structure is defined in STDLIB.H.

/* DIV.C: This example takes two integers as command-line arguments and
* displays the results of the integer division. This program accepts
* two arguments on the command line following the program name, then
* calls div to divide the first argument by the second. Finally,
* it prints the structure members quot and rem.

x is 876, y is 13
The quotient is 67, and the remainder is 5
