Question

问题遇到的现象和发生背景

不管怎么样输出的工资都是0.00000000，，很奇怪

#include<stdio.h>
int main()
{
    const double RATE =8.25;
    const int STANDARD =40;
    double pay = 0.0;
    int hours=0;

printf("请输入工作的小时数：");
scanf("%d", &hours);
printf("\n");
if (hours>STANDARD)
    pay = STANDARD * RATE +(hours-STANDARD)*(RATE*1.5);

else
    pay = hours* RATE;
printf("应付工资：%f\n", &pay); 
}

```
