scanf函数的输出问题


#include 
int main(void)
{
    float weight,value;
    //假设白金的价格为每（金衡）盎司￥1700，单位换算机制详见P34
    value=1700*weight*14.5833;
 
    printf("Are you worth you weight in platinum?\n");
    printf("let's check it out.\n");
    printf("Please enter your weight in pounds.\n");
 
    //新函数scanf:用于获取用户输入
    getchar();
    scanf_s("%f",&weight);
    getchar();
    printf("So your weight in platinum is worth $%.2f.\n",value);
    printf("You are easily worth that! If platinum prices drop,\n");
    printf("eat more to maintain your value.\n");
 
    return 0;
}

第16行代码中value的值无法赋到转换说明处，显示结果仍为0.00

14行为啥要getchar()
你输入的是weight，但输出的是value.
你应该将15行放到第6行，先输入再计算啊
