c語言 函數的參數傳遞示例

C ++ isgreaterequal()函數 (C++ isgreaterequal() function)

isgreaterequal() function is a library function of cmath header, it is used to check whether the given first value is greater than or equal to the second value. It accepts two values (float, double or long double) and returns 1 if the first value is greater than or equal to the second value; 0, otherwise.

isgreaterequal()函數是cmath標頭的庫函數，用于檢查給定的第一個值是否大于或等于第二個值。 它接受兩個值( float ， double或long double )，如果第一個值大于或等于第二個值，則返回1；否則，返回1。 0，否則。

Syntax of isgreaterequal() function:

isgreaterequal()函數的語法：

In C99, it has been implemented as a macro,

在C99中，它已實現為宏，

macro isgreaterequal(x, y)

In C++11, it has been implemented as a function,

在C ++ 11中，它已作為函數實現，

bool isgreaterequal (float x , float y);bool isgreaterequal (double x , double y);bool isgreaterequal (long double x, long double y);

Parameter(s):

參數：

• x, y – represent the two values to be checked whether x is greater than or equal to the y.

  x，y –表示兩個要檢查的值，即x是否大于或等于y 。

Return value:

返回值：

The returns type of this function is bool, it returns 1 if x is greater than or equal to y; 0, otherwise.

該函數的返回類型為bool ，如果x大于或等于y ，則返回1；否則，返回1。 0，否則。

Example:

例：

Input:float x = 10.0f;float y = 5.0f;Function call:isgreaterequal(x, y);Output:1

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

// C++ code to demonstrate the example of // isgreaterequal() function#include <iostream> #include <cmath> using namespace std;int main() {cout << "isgreaterequal(0.0f, -2.0f) : " << isgreaterequal(0.0f, -2.0f) << endl;cout << "isgreaterequal(10.0f, 20.0f) : " << isgreaterequal(10.0f, 20.0f) << endl;cout << "isgreaterequal(10.0f, 10.0f) : " << isgreaterequal(10.0f, 10.0f) << endl;cout << "isgreaterequal(-10.0f, -20.0f): " << isgreaterequal(-10.0f, -20.0f) << endl;float x = 10.0f;float y = 5.0f;// checking using the conditionif (isgreaterequal(x, y)) {cout << x << " is greater than or equal to " << y << endl;}else {cout << x << " is not greater than or equal to " << y << endl;}x = 10.0f;y = 10.0f;if (isgreaterequal(x, y)) {cout << x << " is greater than or equal to " << y << endl;}else {cout << x << " is not greater than or equal to " << y << endl;}return 0; }

Output

輸出量

isgreaterequal(0.0f, -2.0f) : 1 isgreaterequal(10.0f, 20.0f) : 0 isgreaterequal(10.0f, 10.0f) : 1 isgreaterequal(-10.0f, -20.0f): 1 10 is greater than or equal to 5 10 is greater than or equal to 10
