C++ ldiv() function

ldiv() 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 ldiv() function:

C++11:

ldiv_t ldiv (long int numer, 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 ldiv_t, returns a structure that contains the quot (quotient) and rem (remainder).

Sample Input and Output

Input:
long int n = 123456789;
long int d = 12345678;
ldiv_t result;

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

Output:
result.quot = 10
result.rem = 9

Example

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

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

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

// main() section
int main()
{

    long int n = 123456789;
    long int d = 12345678;
    ldiv_t result;

    result = ldiv(n, d);

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

    n = 999988887777;
    d = 1112223334;

    result = ldiv(n, d);

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

    n = 100100234;
    d = 9878762536;

    result = ldiv(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  : 123456789
Denominator: 12345678
Quotient   : 10
Remainder  : 9

Numerator  : 999988887777
Denominator: 1112223334
Quotient   : 899
Remainder  : 100110511

Numerator  : 100100234   
Denominator: 9878762536
Quotient   : 0
Remainder  : 100100234
