和JAVA中選擇?

編程屆有一個固有的偏見,就是大家默認C++可以輕松轉JAVA,但JAVA轉C++很難。

實際情況比較復雜,通常來說,JAVA在軟件工程上的訓練比C++足,但是缺乏內存管理和硬件優化的訓練。

如果是科班在校同學,我強烈建議學一遍 C++,

如果你是轉行、轉專業,急著找工作的話,那我還是建議學習 Java , 以后想提升的時候,還是可以再學習C++ 的.。

你如果選擇C++ , 那C++ 的難度與JAVA 比,那應該不在一個層次. 因為 C++ 作者及委員會 想給你帶來足夠的抽象能力, 讓你可以抽象這個世界;

給你足夠的自由與控制硬件的能力,及零開銷的高性能.

「零成本抽象」是一種語言特性的標準,C++ 有的特性是零成本的,但并不是所有的特性都是零成本的,比如虛表。

實際上,經驗豐富的 C++ 程序員應該可以很容易轉到 Java 上來,因為他們真的有很多相似之處。

基本語法是完全一樣的,只是 Java 砍掉了大量的 C++ 特性,僅僅保留了類相關的部分,在 Java 的世界里,一切都是類。

C++博大精深,并且和計算機底層關系緊密,如果不是想走培訓班路線,迅速就業,那首推好好學習C++。

尤其對于科班學生來說,把C++學好,再學通之后再學其他語言,這種感覺誰試誰舒爽!

推薦以下C+書籍:

《C++ primer》《Essential c++》 《C++編程思想》 《effective C++》《more effective C++ 》《Think in C++》《C++ primer plus》《C++ coding standard》

對于計算機專業的學生而言,讀C++計算機經典書籍不光能讓你快速提升知識和能力,更會讓你在校招之際如虎添翼。
