“__VA_ARGS__是一个预处理宏，用于表示可变数量的参数。当在宏定义中使用__VA_ARGS__，它会自动展开为传递给宏的实际参数。以下是一个示例使用__VA_ARGS__的宏定义代码：
#include <stdio.h>
 
#define PRINT_ARGS(...) printf(__VA_ARGS__)
 
int main() {
    PRINT_ARGS("Hello, %s!\n", "World");
    return 0;
}
上述代码中，宏定义PRINT_ARGS使用__VA_ARGS__来表示可变数量的参数，并通过printf函数打印参数。在main函数中，我们调用PRINT_ARGS宏来打印字符串"Hello, World!"。运行结果为输出"Hello, World!"。
总结：__VA_ARGS__是一个用于表示可变数量参数的预处理宏，在宏定义中使用它可以方便地处理不定数量的参数。“----来自百度
