我是一个C++新手.我在这里尝试了我的第一个程序.我的眼睛这个程序是正确的.

#include <iostream>

using namespace std;

class mystruct
{
    private:
        int m_a;
        float m_b;

    public:
        mystruct(int x, float y)
        {
                m_a = x;
                m_b = y;
        }

};


int main()
{

        mystruct m = mystruct(5,3.14);

        cout << "my structure " << m << endl;

        return 0;
}

但是我得到了很多错误.不知道为什么？

cout.cpp: In function ‘int main()’:
