lldiv() function in C++ STL

The lldiv() is a builtin function in C++ STL which gives us the quotient and remainder of the division of two numbers.

Syntax:

lldiv(n, d)

Parameters: The function accepts two mandatory parameters which are described below:

• n: It specifies the dividend. The data-type can be long long or long long int.
• d: It specifies the divisor. The data-type can be long long or long long int.

Return value: The function returns a structure of type lldiv_t which consists of two members: quot and rem, where quot is the quotient and rem is the remainder. The struct is defined as follows:

struct lldiv_t {
long long quot;
long long rem;
};

Below programs illustrate the above function:

Program 1:

 // C++ program to illustrate the // lldiv() function #include #include using namespace std;    int main() {     long long n = 1000LL;     long long d = 50LL;        lldiv_t result = lldiv(n, d);        cout << "Quotient of " << n << "/" << d          << " = " << result.quot << endl;        cout << "Remainder of " << n << "/" << d          << " = " << result.rem << endl;        return 0; }

Output:

Quotient of 1000/50 = 20
Remainder of 1000/50 = 0

Program 2:

 // C++ program to illustrate // the lldiv() function #include #include using namespace std;    int main() {     long long int n = 251987LL;     long long int d = 68LL;        lldiv_t result = lldiv(n, d);        cout << "Quotient of " << n << "/" << d          << " = " << result.quot << endl;     cout << "Remainder of " << n << "/" << d          << " = " << result.rem << endl;        return 0; }

Output:

Quotient of 251987/68 = 3705
Remainder of 251987/68 = 47
