原文： What are some of the best ways to learn programming? 翻譯＆筆記自目前Upvoted數最高的答案： 作者：Kah Keng Tay 有八個選項可以提供給大家做參考，從這些地方入手：

C程序中的字符串 第一課 1-1 字符數組 與 字符串 給數組賦值的基本與法： #include <iostream> using namespace std; int main () {     char a [ 10 ] = { 'a' , 'b' , 'c' , 'd' , 'e' , 'f' , 'g' , 'h' , 'i' , 'j' };     for ( int i = 0 ; i < 10 ; i ++)    cout << a [ i ];     return 0; } ＊若是沒有給予足夠的初始值，暫存器會以 \0 來做存取，而再匯出時則會停於 \0 之處 若是沒有給予數組常量表達式，則會自動依序補上數組：

計算導論與 C 語言基礎：第九週（C語言的基本成分 ——  C程序的數組） Part I : 一維數組初始化 注意：數組中的數字必須是個常數，若為 a[ i ] 也須定義 i 為一常數

C 語言的基本成分 —— 控制成分

C語言中的數據成分 Part II

C語言中的數據成分 Part I 在C程序語言中，變量 必須 先定義再使用 程式中可以改變的值＝＝>變量 C/C++程序中的數據類型

本文為個人用於筆記 Coursera 課程：計算導論與 C 語言基礎中的課堂筆記。 本次課幫助大家了解 C 語言的歷史，了解 C 語言規範（Specification）的版本演進，了解 C 語言的規範是一個“寬鬆”的規範；在此基礎上，我們將闡述一門程序設計語言所包含的四種基本成分（如上所述）。 焦點問題： 為什麼相同的 C 程序在不同的 C 程序編譯器上，會編譯出不同的結果？

So if you want to buy car, you know the car speed and you don't consider the car price or the car condition, so it is your thought, it is the algorithm you buy a car. For computer, we give them the program ===>for them to do algorithm, but now we try to write done in Pseudocode. Pseudocode write in "spoken language" which help us to understand the problem so we can translate them into computer language ==>JAVA Code.org maybe it could help you have fun from learning code
