尝试学习C#,我对这个VendingMachine问题感到沮丧。
这就是我到目前为止所得到的。
class VendingMachine
{
public int Coke = 20;
public int Beer = 20;
public int LemonLime = 20;
public int Grape = 20;
public int CreamSoda = 20;
public void VmContent()
{
Console.WriteLine("Choose a Drink.");
Console.WriteLine("1. Coke - $1.00\n" +
"2. Beer - $1.00\n" +
"3. Lemon Lime - $1.00\n" +
"4. Grape - $1.50\n" +
"5. Cream Soda - $1.50\n");
}
public void Math()
{
var input = Console.ReadKey();
switch (input.Key)
{
case ConsoleKey.D1:
var i = Beer - 1;
i = Beer;
Console.WriteLine("You Got a Coke");
Console.WriteLine($"Total Coke Left: {i}");
break;
}
}
}
我只是想弄清楚如何从每个内容的总数中减去。
而我在交换机中到达那里。
真的没有用。
最佳答案
您想从主变量中减去,像这样:
Coke--; //Or Coke = Coke - 1;
Console.WriteLine("You Got a Coke");
Console.WriteLine($"Total Coke Left: {Coke}");
break;
