C ++ llabs()函數(shù) (C++ llabs() function)

llabs() function is a library function of cstdlib header. It used to get the absolute of the given value. This function is similar to the abs() and labs() functions except for the type of the parameter, it is used for the long long integer values. It accepts a parameter and returns the absolute value.

llabs()函數(shù)是cstdlib標(biāo)頭的庫(kù)函數(shù)。 它用來(lái)獲取給定值的絕對(duì)值。 除了參數(shù)的類型外，此函數(shù)與abs()和labs()函數(shù)類似，它用于long long整數(shù)值。 它接受一個(gè)參數(shù)并返回絕對(duì)值。

Syntax of llabs() function:

llabs()函數(shù)的語(yǔ)法：

C++11:

C ++ 11：

long long int llabs (long long int n);

Parameter(s):

參數(shù)：

• n – represents the value whose absolute value to found.

  n –表示要找到其絕對(duì)值的值。

Return value:

返回值：

The return type of this function is long long int, it returns the absolute value.

該函數(shù)的返回類型為long long int ，它返回絕對(duì)值。

Example:

例：

Input:n = -1234567890987654321Function call:llabs(n);Output:1234567890987654321Input:n = 1234567890987654321Function call:llabs(n);Output:1234567890987654321

C ++代碼演示llabs()函數(shù)的示例 (C++ code to demonstrate the example of llabs() function)

// C++ code to demonstrate the example of // llabs() function#include <iostream> #include <cstdlib> using namespace std;// main() section int main() {long long int n;n = -1234567890987654321;cout << "llabs(" << n << "): " << llabs(n) << endl;n = 1234567890987654321;cout << "llabs(" << n << "): " << llabs(n) << endl;n = -1111222233334444555;cout << "llabs(" << n << "): " << llabs(n) << endl;n = 1111222233334444555;cout << "llabs(" << n << "): " << llabs(n) << endl;return 0; }
