C ++ isgreater()函数 (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()函数是cmath标头的库函数，用于检查给定的第一个值是否大于第二个值。 它接受两个值( float ， double或long double )，如果第一个值大于第二个值，则返回1；否则，返回1。 0，否则。

Syntax of isgreater() function:

isgreater()函数的语法：

In C99, it has been implemented as a macro,

在C99中，它已实现为宏，

    macro isgreater(x, y)

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

在C ++ 11中，它已作为函数实现，

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

Parameter(s):

参数：

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

  x，y –表示两个要检查的值，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.

该函数的返回类型为bool ，如果x大于y ，则返回1；否则，返回1。 0，否则。

Example:

例：

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

C ++代码演示isgreater()函数的示例 (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

输出量

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
