tmp = 2/4;竟然没有发现的

                                            我还纠结着单目运算符和双目运算符和乘除的一些优先级什么事情。

#include <stdlib.h>

//#define

static float x = 2.5, y = 4.7;

int main()
{
    
    int tmp = 2 / 4;
    //x+y 
    printf("类型转换is %f\n",x+a%3*(int)(x + y)%2/4);
    printf("tmp is %d\n", tmp);

    while (1)
    {
        getchar();
    }

    return 0;
}
