十进制到十六进制转换

#include<iostream.h>
class a
{
	int b;
public:
	void infer()
	{
		cout<<"请输入一个整数"<<endl;
		cin>>b;
	}
	void turn()
	{
		cout<<hex<<b<<endl;
	}
};
void main()
{
	for(int j=0;;j++)
	{
		a c;
	    c.infer();
	    cout<<"则其十六进制为"<<endl;        
	    c.turn();
		int i;
		cout<<"如果想继续输入请按1，否则按0"<<endl;
		cin>>i;
		if(i)
			continue;
		else
			break;
	}
