运行结果:
x= 10
y= 10
Unload me
x=0
y=10

为什么结果会是这样的呢,我预期的结果是:

x= 10
y= 10
Unload me
x=0
y=0

谢谢!
*/

为什么预期是
x= 10
y= 10
Unload me
x=0
y=0

结果并不能预期~

x= 10
Y= 10
Unload me
x= -572662307
Y= -572662307


这是用非dev-cpp运行的结果！
明白了吧！呵呵~

版主高明,知道我用的是dev-c,我真是笨死了,我有四五个编译器,乍地就不用它们试试看.
谢谢!

HJin兄,你的代码我copy下载编译会出错,怎么回事?
错误指向这句:(上面的是出错提示)
point::point(int x_,int y_) : x(x_), y(y_)
{
}
