C ++ ldiv()函數 (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()函數是cstdlib標頭的庫函數。 它用于整數除法，它接受兩個參數( 分子和分母 )，并返回一個包含quot ( 商 )和rem ( remaind )的結構。

Syntax of ldiv() function:

ldiv()函數的語法：

C++11:

C ++ 11：

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

Parameter(s):

參數：

• 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).

該函數的返回類型為ldiv_t ，返回一個包含quot ( quotient )和rem ( 其余部分 )的結構。

Example:

例：

Input:long int n = 123456789;long int d = 12345678;ldiv_t result;Function call:result = ldiv(n, d);Output:result.quot = 10result.rem = 9

C ++代碼演示ldiv()函數的示例 (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;cout << "Denominator: " << d << endl;cout << "Quotient : " << result.quot << endl;cout << "Remainder : " << result.rem << endl;cout << endl;return 0; }
