Question

问题是:

Please enter the number of gallons of gasoline: 100
Original number of gallons is: 100
100 gallons is the equivalent of 378.54 liters
Thanks for playing

如何显示“原始加仑数为:100”我的“感谢参与”与“按任意键继续”结合在一起，我不知道如何将它们分开。

#include <iostream>
 using namespace std;
int main()
{
float g;
float l;

cout << "Please enter the number of gallons of gasoline ";
cin >> g;

l = g*3.7854;
cout << g << " Gallon is the equivalent of " << l << "liters" << endl;

cout << "Thank you for playing";

system("pause");
return 0;

}

Answer 1

1. Do not use "use namespace std;" ，这是不好的做法。

2. Using system("pause") is also bad practice .

3. 使用

   std::cout << std::endl;
   

输出换行符，分隔不同的文本行。
