#include

int main()
{
struct Sales_data
{
std::string bookNo;
unsigned int units_sold;
double revenue;
};

Sales_data data1, data2;
double price = 0; 

std::cin >>"请输入INBN: ">>data1.bookNo;

std::cin>>"请输入售出书册数：" >> data1.units_sold;
std::cin >>"请输入本书单价" >> price;
data1.revenue = data1.units_sold * price;

std::cin >>"请输入相同的INBN: ">>data2.bookNo;

std::cin>>"请输入售出书册数：" >> data2.units_sold;
std::cin >>"请输入本书单价" >> price;
data2.revenue = data2.units_sold * price;

if (data1.bookNo == data2.bookNo)
{
    unsigned totalCnt = data1.units_sold + data2.units_sold;
    double totalRevenue = data1.revenue + data2.revenue;

    std::cout << "INBN为 "<<data1.bookNo << "的这本书售出总册数为： " << totalCnt 
              << " 总销售额为 " << totalRevenue << " ";
if (totalCnt != 0)
    std::cout <<"平均价格为："<< totalRevenue/totalCnt << std::endl;
else
        std::cout  << "(no sales)" << std::endl;

    return 0;  
} 
else {  
    std::cerr << "Data must refer to the same ISBN" 
              << std::endl;
    return -1; 
}

}

Answer 1

你的cin用法错了吧

把类似这些的

 std::cin >>"请输入INBN: ">>data1.bookNo;

都改成

 std::cout <<"请输入INBN: ";
 std::cin >>data1.bookNo;

试试
