为什么数组索引是基于大多数编程语言为零？ [英] Why array indexes are zero based in most programming languages?

问题描述

C ++，C＃，C，D，Java的，......是从零开始的。

Matlab是我唯一知道的语言，从1开始。

解决方案

阵列基于C和C零

++作为重present的从项目列表的开始偏移。

这两条线都在C相同的结果。

  anArray [3] = 4;
*（anArray +3）= 4;
 

首先是标准索引第二个采用指针增加了三到ID，然后dereffrences它。这是相同的索引器。

C++, C#, C, D, Java,... are zero based.

Matlab is the only language I know that begin at 1.

解决方案

Arrays are zero based in c and c++ as the represent the offset from the beginning of the list of the item.

These two lines have identical result in c.

anArray[3] = 4;
*(anArray +3) = 4; 

The first is the standard indexer the second takes the pointer adds three to id and then dereffrences it. Which is the same as the indexer.
