}
cout<}
void main()

highway X;
while(1)
{

X.process();cout<<"卢姣 080806110103"<}
}

highway类的成员变量没有初始化。
无参构造函数里也加一句的car=carfee=bus=busfee=truck=truckfee=0;

#include
class highway
{int car;
int bus;
int truck;
//int a,b,c;
public:
// highway(){}
int Q;
highway()
{
car=bus=truck=0;
//a=x;b=y;c=z;
}
~highway(){cout<<"卢姣 080806110103"<void car_increment();
void bus_increment();
void truck_increment();
void income();
void process();
};
void highway::car_increment(){++car;Q+=5;cout<<"已经"<void highway::bus_increment(){++bus;Q+=15;cout<<"已经"<void highway::truck_increment(){++truck;Q+=25;cout<<"已经"<void highway::income(){cout<<"Q="<void highway::process()
{//char ch;
int ch;
cout<<"欢迎来到高速公路收费站"< cout<<"**********************\n"< cout<<" 小车过路：请击1 "< cout<<" 客车过路：请击2 "< cout<<" 货车过路：请击3 "< cout<<" 退出并统计：请击0 "< cout<<"**********************\n"< cout<<"请输入您的选择:"< cin>>ch;
switch(ch)
{
case 1:car_increment();break;
case 2:bus_increment();break;
case 3:truck_increment();break;
case 0:income();break;
}
cout<}
void main()
{ static highway X;
X.Q=100;
while(1)
{

cout<<"给出收费站目前收款状况："<< X.Q<
X.process();
}
} 我按我所了解去修改，意思应该能表达了
