发帖数: 32122 | 1 There are 20 Programming Languages in the World where the array index starts
from 1 and not from 0. Some of the popular languages include R, COBOL,
Matlab and Julia.
Most programmers think that array indices start with 0 always but this is
not the case. The start index of 0 or 1 is decided based on various factors.
The 20 Programming Languages where indices start from 1 (NOT 0) are:
ALGOL 98
APL
AWK
CFML
COBOL
Fortran
FoxPro
Julia
Lingo
Lua
Mathematica
Matlab
PL/I
RPG
R
Ring
Sass
Smalltalk
Wolfram Language
XPath/ XQuery |

不過index-1的語言，不是設計人數學沒學好，就是針對數學沒學好的用戶。

发帖数: 4406 | 6 其實如果是矩陣或者運算，0還是1區別不大。問題是一旦和內存地址做運算，0是最自
然的選擇。Fortran因爲自己基本上把語言限定在了科學計算的範疇，這個設計其實還
OK。再說Fortran是可以指定0還是1 index的。
”數學學好“是指在設計語言的時候選取最自洽的設計方式，不是說語言只能用來做數
學計算。
