#include<iostream>
using namespace std;
#define New_Variable(name, i) int name##i

int main()
{
	cout<<"hello main"<<endl;

	New_Variable(Variable, 0) = 3;
	New_Variable(Variable, 1) = 4;
	int result = Variable0 + Variable1;

	cout<<"Variable0: "<<Variable0<<endl;
	cout<<"Variable1: "<<Variable1<<endl;
	cout<<"result: "<<result<<endl;

	cout<<"goodbye main"<<endl;
	return 0;
}

运行结果：

hello main
Variable0: 3
Variable1: 4
result: 7
goodbye main
