Blocks下的第一个C++程序

 main.cpp:
#include <iostream>
#include <exception>

using namespace std;

class Test
{
public:
string name;
long id;
bool pass;
public:
void getUser()
{
pass=false;
while(pass==false)
{
try{
pass=true;
cout<<"Input your id:"<<endl;
cin>>id;
if(cin.fail()) //判读输入是不是正确的
{
throw new exception;
}
cout<<"Input your name:"<<endl;
cin>>name;
//下面是不用异常处理方法做的。注意里面的continue，其实这是针对上面cin>>id写的。
if(cin.fail())
{
pass=false;
cin.clear();
cout<<"Your name is wrong,please input again!"<<endl;
continue;
}
}catch(exception* e)//这里要用exception*不然会编译会出错
{
pass=false;
cout<<"Your inputing is wrong,please input again!"<<endl;
cin.clear();//cin.clear()方法很重要，如果不掉用，则cin异常不会终止，那么程序就进入了死循环
delete e;
}
}

}
void display()
{
cout<<"This is my first class processed in linux!"<<endl;
cout<<"my name is "<<name<<endl;
}
};
int main()
{
Test* tt= new Test();
tt->getUser();
tt->display();
return 0;
}
