好东西,绝对是好东西,我向大家推荐

#include <iostream.h>
int main()
{
	int N,n;
	int a[80];
	int i;
	while(cin>>n)
	{
		cin>>N;
		i=0;
		while(n>=N)
		{
			a[i]=n%N;
			n=n/N;
			i++;
		}
		a[i]=n;
		for(;i>=0;i--)
		{
			if(a[i]<10) {cout<<a[i];}
				else
				{
					switch(a[i])
						{
							case 10: cout<<"A";break;
					                case 11: cout<<"B";break;
					                case 12: cout<<"C";break;
							case 13: cout<<"D";break;
							case 14: cout<<"E";break;
							case 15: cout<<"F";break;
				         	}
				}
		}
		cout<<endl;
	}
}
