The function **ldiv** divides numerator by denominator and returns the quotient and remainder of the division. It returns a structure of type ldiv_t, which has two members: quot(quotient) and rem(remainder).

## Function prototype of ldiv

*ldiv_t ldiv(long int numerator, long int denominator);***numerator**: This is a long integer representing the numerator.**denominator**: This is a long integer representing the denominator.

## Return value of ldiv

This function returns the quotient and remainder of numerator/denominator as a ldiv_t type(defined in stdlib library) which has two members quot(quotient) and rem(remainder).

## C program using ldiv function

The following program shows the use of ldiv function to find quotient and remainder of long integer division.

#include <stdio.h> #include <stdlib.h> int main(){ long int numerator, denominator; ldiv_t response; printf("Enter numerator and denominator\n"); scanf("%ld %ld", &numerator, &denominator); response = ldiv(numerator, denominator); printf("Remainder of %ld/%ld is %ld\n", numerator, denominator, response.rem); printf("Quotient of %ld/%ld is %ld\n", numerator, denominator, response.quot); return 0; }

Output

Enter numerator and denominator 826847 246 Remainder of 826847/246 is 41 Quotient of 826847/246 is 3361
