二、1.封裝、繼承、多態;2.傳值、傳址;3.Template;4.~student();5.私有;6.參數、返回值;7.優先順序、結合性、運算順序;8.代碼的復用、MFC編程;9.X、Y;10.new
⑵ C++語言是一種面向對象的程序設計語言。這個面向對象指的是什麼
面向對象是不同於面向過程的一種編程思想。它是將自己搞不定的事或做起來比較版費力的事委託給信權任的人來做（如VC++中的可視化組具體是怎麼來的，我們不用擔心，只要知道怎麼用就行）；面向過程是事無大小均由自己完成，從底層到頂層，從內部到外部。舉例說明：面向對象像是皇帝，吃喝拉撒都由太監宮女搞定，治理國家由文武百官搞定，他只要會用人、決策、享受主行；而面向過程就像是百姓，吃，自己種地，喝，自己挖井，穿，自己織布等等
