类定义 对象数组

1.类定义；
2.对象数组

#include <iostream>
using namespace std;
class myfoo
{
private:
    int num;
    string foostr;
    
public:
    myfoo(int a,std::string& str ):num(a),foostr(str)
        {          
            cout << "myfoo construt : " << num << endl;
        }

    myfoo()  //myfoo aSmple;如果自己写了构造函数，那么需要列出默认构造

             //  函数
        {
        }
    ~myfoo()
        {
            cout << "myfoo destrut:" << endl;
        }
};
int main(int argc, char* [])
{

    string strtmp("i_love");

    myfoo g[3] = {myfoo(1,strtmp),myfoo(2,strtmp),myfoo(3,strtmp)};
    return 0;
}
