如何在C中使用双宏

#include <stdio.h>

// 定义两个简单的宏
#define SQUARE(x) ((x) * (x))
#define CUBE(x) ((x) * (x) * (x))

int main() {
    int num = 5;
    printf("Square of %d is %d\n", num, SQUARE(num));
    printf("Cube of %d is %d\n", num, CUBE(num));
    return 0;
}

#include <stdio.h>

// 定义两个宏，其中一个宏嵌套了另一个宏
#define MAX(a, b) ((a) > (b) ? (a) : (b))
#define MIN_MAX_DIFF(a, b) (MAX(a, b) - MIN(a, b))

int main() {
    int a = 10, b = 20;
    printf("The difference between max and min of %d and %d is %d\n", a, b, MIN_MAX_DIFF(a, b));
    return 0;
}

#define SUM_SQUARE(a, b) ((a + b) * (a + b))

int x = 5;
int result = SUM_SQUARE(x++, x); // 预期是(5+6)^2，但实际是(5+6)*(5+7)

#define SUM_SQUARE_SAFE(a, b) (((a) + (b)) * ((a) + (b)))
