c语言 div ldiv

C ++ ldiv()函数 (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).

ldiv()函数是cstdlib标头的库函数。它用于整数除法，它接受两个参数( 分子和分母 )，并返回一个包含quot ( 商 )和rem ( remaind )的结构。

Syntax of ldiv() function:

ldiv()函数的语法：

C++11:

C ++ 11：

    ldiv_t ldiv (long int numer, long int denom);

Parameter(s):

参数：

numer – represents the value of numerator.
numer –代表分子的值。
denom – represents the value of denominator.
denom –代表分母的值。

Return value:

返回值：

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

该函数的返回类型为ldiv_t ，返回一个包含quot ( quotient )和rem ( 其余部分 )的结构。

Example:

例：

    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

C ++代码演示ldiv()函数的示例 (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;
