float price;
float count;
public:

{
//cin>>"please input the petrol type,price and count:">>Ptype>>pprice>>Pcount>>endl;
if(Ptype==90||Ptype==93||Ptype==98)
{
type=Ptype;
price=Pprice;
count=Pcount;
}
else cout<<"The petrol type is error,please input again:"<<endl;
}

{
cout<<"the "<<type <<"type count is:"<<price*count<<endl;
return price*count;
}
};

在类的sum（）函数里面你调用process函数后面因该有“（）”吧；
正确应该如下：
void sum(CPetrol a,CPetrol b, CPetrol c)
{
float sum;
sum=a.process()+b.process()+c.process();
cout<<"the sum is:"<<sum<<endl;
};
sum=a.process+b.process+c.process;
改为sum=a.process（）+b.process（）+c.process（）;
就可以了
