Question

我正在制作“假”假期计划指南它要求用户选择一个地点，然后选择他们想要做的活动我似乎无法使其在这种情况下将像199.99这样的小数总计加到全局总计我在这里做什么错了？

//顺便说一下，这一切都在公共主类中

struct rte_eth_dev_info dev_info;
const struct rte_pci_device *pci_dev;
rte_eth_dev_info_get(port, &dev_info);
pci_dev = RTE_DEV_TO_PCI(dev_info.device);


memcmp((const void *)&pci_dev->addr,(const void *)&Input[iLoop].guestpci,sizeof(pcii
_dev->addr))==0) && (rte_memcmp((const void *)&gBtgData.nic_port[port].mac_addr,(const void *)&Input[iLoop]..
mac_addr,sizeof(gBtgData.nic_port[port].mac_addr))==0)

只需将您的价格套餐绑定到Total。

double Total = 0.00; 
        string destination = Console.ReadLine();

        int Destination = Convert.ToInt16(destination);

        switch (Destination)
        {
            case 1:
                {
                    Console.WriteLine("you have selected Barbados! Heres the following excursions you can do!");
                    Console.WriteLine("_________________________!Excursions!_________________________________");
                    Console.WriteLine(" ");
                    Console.WriteLine("Snorkeling in Barbados bay: $199.99 Per Person");
                    Console.WriteLine("Press 1");
                    Console.WriteLine("Barbados Tour Bus Adventure: $59.99 Per Person");
                    Console.WriteLine("Press 2");
                    Console.WriteLine("Barbados Shopping Extravanga: $199.99 Per Person");
                    Console.WriteLine("Press 3");
                    Console.WriteLine("_________________________!Excursions!_________________________________");
                    Console.WriteLine(" ");
                    Console.WriteLine("What is your choice?");

                    string barbadosanswer = Console.ReadLine();
                    int barbadosAnswer = Convert.ToInt32(barbadosanswer);

                    switch(barbadosAnswer)
                    {
                        case 1:
                            Total += 199.99;
                            Console.WriteLine("You have selected Snorkeling in Barbados bay! Your total is currently " + Total);

                        break;
                    }
