Calculate a quotient and remainder
#include <stdlib.h>
div_t div( int numer,
int denom );
- numer
- The numerator in the division.
- denom
- The denominator.

Use the -l c option to

to link against this library.
This library is usually included automatically.
The div() function calculates the quotient and remainder of the
division of numer by denom.
A div_t structure containing the quotient and remainder:
typedef struct {
int quot; /* quotient */
int rem; /* remainder */
} div_t;
#include <stdio.h>
#include <stdlib.h>
void print_time( int seconds )
{
div_t min_sec;
min_sec = div( seconds, 60 );
printf( "It took %d minutes and %d seconds\n",
min_sec.quot, min_sec.rem );
}
int main( void )
{
print_time( 130 );
return EXIT_SUCCESS;
}
produces the output:
It took 2 minutes and 10 seconds
