C ++ isgreater()函數 (C++ isgreater() function)

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

isgreater()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第二個值。 它接受兩個值( float ， double或long double )，如果第一個值大于第二個值，則返回1；否則，返回1。 0，否則。

Syntax of isgreater() function:

isgreater()函數的語法：

In C99, it has been implemented as a macro,

在C99中，它已實現為宏，

    macro isgreater(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 isgreater (float x      , float y);
bool isgreater (double x     , double y);
bool isgreater (long double x, long double y);

Parameter(s):

參數：

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

  x，y –表示兩個要檢查的值，即x是否大于y 。

Return value:

返回值：

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

該函數的返回類型為bool ，如果x大于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:
isgreater(x, y);
Output:
1

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

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

Output

輸出量

isgreater(0.0f, -2.0f): 1
isgreater(10.0f, 20.0f): 0
isgreater(10.0f, 5.0f): 1
isgreater(-10.0f, -20.0f): 1
10 is greater than 5
20 is greater than 10
