The lldiv() function can be thought as long long int version of div().
It is defined in <cstdlib> header file.
Mathematically,
quot * y + rem = x
lldiv() prototype [As of C++ 11 standard]
lldiv_t lldiv(long long int x, long long int y); lldiv_t lldiv(long long x, long long y);
The lldiv() function takes a two arguments x and y, and returns the integral quotient and remainder of the division of x by y.
The quotient quot is the result of the expression x/y. The remainder rem is the result of the expression x%y.
lldiv() Parameters
- x: Represents the numerator.
- y: Represents the denominator.
lldiv() Return value
The lldiv() function returns a structure of type lldiv_t which consists of two members: quot and rem. It is defined as follows:
struct lldiv_t {
long long quot;
long long rem;
};
Example: How lldiv() function works in C++?
#include <iostream>
#include <cstdlib>
using namespace std;
int main()
{
long long nume = 998102910012LL;
long long deno = 415LL;
lldiv_t result = lldiv(nume, deno);
cout << "Quotient of " << nume << "/" << deno << " = " << result.quot << endl;
cout << "Remainder of " << nume << "/" << deno << " = " << result.rem << endl;
return 0;
}
When you run the program, the output will be:
Quotient of 998102910012/415 = 2405067253 Remainder of 998102910012/415 = 17
