Question

我想要制作三个项目然后转换

示例：

item1 + item2 + item3 = `total`

然后，将total转换为沙特里亚尔

// sss.cpp：定义控制台应用程序的入口点。 //

#include "stdafx.h"
#include "iostream"

int _tmain(int argc, _TCHAR* argv[])
{
    return 0;
}


 using namespace std;
 int main()
 {
 cout << "conver from US dollar to Saudi ryals" << endl;
 double dollars1;
 double dollars2;
 double dollars3;
 double ryals = 3.75;
 cout << "Enter the amount of money you would like to transfer item 1" << endl;
 cin >> dollars1;
 cout << "Enter the amount of money you would like to transfer item 1" << endl;
 cin >> dollars2;
 cout << "Enter the amount of money you would like to transfer item 1" << endl;
 cin >> dollars3;
 cout << "US $" << dollars1 + dollars2 + dollars3 << " equals " << ryals * (dollars1 +        dollars2 + dollars3) << " Saudi ryals." << endl;
 cout << "that's it" << endl;
 cin.get();
 cin.get();
 }

今天美元兑沙特里亚尔的汇率为1美元兑3.75里亚尔。

你的逻辑在这里似乎是正确的：ryals * ( dollars1 + dollars2 + dollars2)但是对于初学者你有两个主管。在任何情况下都不会发生这种情况。另外，我会重新考虑dollars1, dollars2, dollars3

的命名惯例

您的#include <stdafx>是由Visual Studio自动生成的，这就是为什么我假设为您创建了两个主电源。有关详细信息，请参阅here。

试试这个：

#include "iostream"

     using namespace std;
     int main()
     {
     cout << "conver from US dollar to Saudi ryals" << endl;
     double dollars1;
     double dollars2;
     double dollars3;
     double ryals = 3.75;
     cout << "Enter the amount of money you would like to transfer item 1" << endl;
     cin >> dollars1;
     cout << "Enter the amount of money you would like to transfer item 1" << endl;
     cin >> dollars2;
     cout << "Enter the amount of money you would like to transfer item 1" << endl;
     cin >> dollars3;
     cout << "US $" << dollars1 + dollars2 + dollars3 << " equals " << ryals * (dollars1 +        dollars2 + dollars3) << " Saudi ryals." << endl;
     cout << "that's it" << endl;
     cin.get();

 }
