简单的C++题

#include <iostream>
using namespace std;
int main(){
	int a;//四位数字
	cin>>a;
	int gw,sw,bw,qw;
	gw=a%10;
	sw=a%100/10;
	bw=a/100%10;
	qw=a/1000;
	
	gw=(gw+5)%10;
	sw=(sw+5)%10;
	bw=(bw+5)%10;
	qw=(qw+5)%10; 
	cout<<qw<<" "<<bw<<" "<<sw<<" "<<gw<<endl;

	cout<<gw*1000+sw*100+bw*10+qw;
	return 0; 
}
