基本程式語法整理 Python, PHP, JS, Java, C#, C, C++

最近學C、C++,想一塊學,因為大學程式的緣故,我想,我還是先修好了,練習演算法,順便複習以前的程式。我已經語法大混亂了,沒有編譯器糾正我,基本很難寫正確程式,除非最近都在攻某個專案,否則我平時都是一天寫好幾種不同語言的程式,函數偶爾會亂調用。我知道有些工程師很討厭什麼語言都碰一點的人,但,我不管啦,我就是什麼都學,反正最後我也只會主攻少數幾項,也不至於什麼語言都很淺。

The strong do what they can and the weak suffer what they must.

Privacy is your right and ability to be yourself and express yourself without the fear that someone is looking over your shoulder and that you might be punished for being yourself, whatever that may be.

It is quality rather than quantity that matters.

I WANT Internet Freedom.

Reality made most of people lost their childishness.
