C++ lldiv() function

lldiv() function is a library function of cstdlib header. It is used for integral division, it accepts two parameters (numerator and denominator) and returns a structure that contains the quot (quotient) and rem (remainder).

Syntax

Syntax of lldiv() function:

C++11:

lldiv_t lldiv (long long int numer, long long int denom);

Parameter(s)

• numer – represents the value of numerator.
• denom – represents the value of denominator.

Return value

The return type of this function is lldiv_t, returns a structure that contains the quot (quotient) and rem (remainder).

Sample Input and Output

Input:
long long int n = 1111222233334444555;
long long int d = 1111222233334444;
lldiv_t result;

Function call:
result = lldiv(n, d);

Output:
result.quot = 1000
result.rem = 555

Example

C++ code to demonstrate the example of lldiv() function:

// C++ code to demonstrate the example of
// lldiv() function

#include <iostream>
#include <cstdlib>
using namespace std;

// main() section
int main()
{

    long long int n = 1111222233334444555;
    long long int d = 1111222233334444;
    lldiv_t result;

    result = lldiv(n, d);

    cout << "Numerator  : " << n << endl;
    cout << "Denominator: " << d << endl;
    cout << "Quotient   : " << result.quot << endl;
    cout << "Remainder  : " << result.rem << endl;
    cout << endl;

    n = 1234567890987654321;
    d = 1000000000000000000;

    result = lldiv(n, d);

    cout << "Numerator  : " << n << endl;
    cout << "Denominator: " << d << endl;
    cout << "Quotient   : " << result.quot << endl;
    cout << "Remainder  : " << result.rem << endl;
    cout << endl;

    n = 1234567890000000000;
    d = 1234567890000000000;

    result = lldiv(n, d);

    cout << "Numerator  : " << n << endl;
    cout << "Denominator: " << d << endl;
    cout << "Quotient   : " << result.quot << endl;
    cout << "Remainder  : " << result.rem << endl;
    cout << endl;

    return 0;
}

Output

Numerator  : 1111222233334444555
Denominator: 1111222233334444
Quotient   : 1000
Remainder  : 555

Numerator  : 1234567890987654321
Denominator: 1000000000000000000
Quotient   : 1
Remainder  : 234567890987654321

Numerator  : 1234567890000000000
Denominator: 1234567890000000000
Quotient   : 1
Remainder  : 0
