#include<iostream>
    
    void main() //void表示无return
    {
    	using namespace std;
    	cout << "Tom" << endl;
    	cout << "Chengdu" << endl;

注：如果遇到VS 2017 运行C++程序时控制台输出窗口一闪而过的问题，那是运行完毕了，不过没来得及显示。对此，可以通过在网上搜教程改vs设置来解决(推荐)，也可以在句尾加一条指令system("pause");

#include<iostream>
    
    void main(int Long, int Ma)
    {
    	using namespace std; 
    	cout << "Please input distance in Long;";
    	cin >> Long; //输入
    	Ma = 220 * Long;
    	cout << "Distance in Ma is " << Ma << endl;
    	//system("pause");
    }
