帮我看看这个类定义有啥问题

djklhm

代码如下：
[quote#include <iostream>
using namespace std;

class Sample
{
    private:
        int x,y;
    public:
        void setvalue(int x1,int y1);
        void display();
};

void Sample::setvalue(int x1,int y1)
{
    x=x1;y=y1;
}

void Sample::display()
{
    cout&lt;&lt;"x="&lt;&lt;x&lt;&lt;",y=""&lt;&lt;y&lt;&lt;endl;
}

int main()
{
    Sample acc;
   
    acc.setvalue(3,33);
    acc.display();
   
    return 0;
}
[/quout]
编译错误报告如下：
[quote]D:/yzf/c/lx6.cpp:20:25: warning: multi-line string literals are deprecated
D:/yzf/c/lx6.cpp:20:25: missing terminating " character

代码如下：

#include

class Sample

private:
int x,y;
public:
void setvalue(int x1,int y1);
void display();
};

void Sample::setvalue(int x1,int y1)

}

void Sample::display()
{
cout&lt;&lt;"x="&lt;&lt;x&lt;&lt;",y=""&lt;&lt;y&lt;&lt;endl;
}

int main()
{
Sample acc;

acc.setvalue(3,33);
acc.display();

return 0;
}

void Sample::display()
{
cout&lt;&lt;"x="&lt;&lt;x&lt;&lt;",y=""&lt;&lt;y&lt;&lt;endl;    // 明显多了一个 "
}

#include <iostream>   // 至少应该跟一个文件名吧

djklhm

我也反先了，谢谢你

djklhm

#include后面跟的有文件名，但不知道为何没有显示出来

Ivn

用 code src /code 不要用 [quote]

djklhm

谢谢，我以前不知道，试一试

我试了两次，发现用"quote"，“#include <iostream>”的后半部分“<iostream>”会被截断丢掉。谢谢斑竹
