c语言判断奇数偶数

There are many ways to check whether a given number is EVEN or ODD, which we have already wrote in other posts; here you can also read them

检查给定数字是EVEN还是ODD的方法有很多，我们已经在其他帖子中写过； 在这里您还可以阅读它们

• Check EVEN or ODD using if function.

  使用if函数检查EVEN或ODD。

• Check EVEN or ODD using bitwise operator (without using modulus (%) operator).

  使用按位运算符检查EVEN或ODD(不使用模数(％)运算符)。

• Check EVEN or ODD using switch statement.

  使用switch语句检查EVEN或ODD。

There is another way, which we are going to implement here...

还有另一种方法，我们将在这里实现...

We will check whether a given number is EVEN or ODD by using Macro (Read more: Macro in C). In the Macro definition, we will use condition operator (ternary operator) to validate the conditions.

我们将使用Macro检查给定的数字是EVEN还是ODD (更多信息： C中的Macro )。 在宏定义中，我们将使用条件运算符 (三元运算符)来验证条件。

C程序使用C中的宏检查EVEN或ODD (C program to check EVEN or ODD using Macros in C )

Macro definitions:

宏定义：

    #define ISEVEN(n)   ((n%2 == 0) ? 1 : 0)
#define ISODD(n)    ((n%2 != 0) ? 1 : 0)

Program:



程序：

</ s> </ s> </ s>

#include <stdio.h>
#define ISEVEN(n)   ((n%2 == 0) ? 1 : 0)
#define ISODD(n)    ((n%2 != 0) ? 1 : 0)
int main(void)
{int number;
printf("Enter an integer number: ");
scanf("%d",&number);
if(ISEVEN(number))
printf("%d is an EVEN number\n",number);
else if(ISODD(number))
printf("%d is an ODD number\n",number);
else
printf("An Invalid Input\n");
return 0;
}

Output

输出量

    First run:
Enter an integer number: 100
100 is an EVEN number
Second run:
Enter an integer number: 101
101 is an ODD number

We can also use One Macro to validate both (EVEN or ODD)



我们还可以使用一个宏来验证两者(偶数或奇数)

</ s> </ s> </ s>

if(ISEVEN(number))
printf("%d is an EVEN number\n",number);
else
printf("%d is an ODD number\n",number);
