关于一个计算运费的程序

Question

#include
#include
using namespace std;
void main()
{
int dist, distance;
double price=100, wright,discount, freight;
cout << "请输入货物的重量（吨）和路程（千米）\n";
cin >> wright >> distance;
dist = distance / 250;
switch (dist)
{
case0:discount = 0; break;
case1:discount = 2; break;
case2:discount = 5; break;
case4:discount = 8; break;
case8:discount = 10; break;
case12:discount = 15; break;
}
cout << "折扣：" << -discount << "%" << endl;
freight = price * wright * distance * (1 - discount / 100.0);
cout << "运费：" << freight << endl;
system("pause");
}

请大家帮我看看哪儿有错啊，我实在找不到啊！

Answer 1

case 0之间要加空格
之后的case也是

#include<iostream> 
using namespace std;
int main()
{
int dist, distance;
double price=100, wright,discount, freight;
cout << "请输入货物的重量（吨）和路程（千米）\n";
cin >> wright >> distance;
dist = distance / 250;
switch (dist)
{
case 0:discount = 0; break;
case 1:discount = 2; break;
case 2:discount = 5; break;
case 4:discount = 8; break;
case 8:discount = 10; break;
case 12:discount = 15; break;
}
cout << "折扣：" << -discount << "%" << endl;
freight = price * wright * distance * (1 - discount / 100.0);
cout << "运费：" << freight << endl;
system("pause");
}
