阿木博主一句话概括:Snobol4【1】 语言在身份证号【2】校验码【3】转换中的应用
阿木博主为你简单介绍:
身份证号校验码是身份证号码中用于验证身份证真实性的关键部分。本文将探讨如何使用 Snobol4 语言,一种古老的编程语言,来实现身份证号校验码的转换和验证。Snobol4 语言以其简洁和强大的文本处理能力而著称,非常适合处理这类字符串操作问题。

一、
身份证号校验码是根据身份证号码前17位数字按照特定算法【4】计算得出的。在中国,身份证号码由18位数字组成,其中最后一位是校验码。校验码的计算方法如下:
1. 将身份证号码前17位数字分别乘以不同的系数【5】(从左至右分别为:7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2)。
2. 将这17个乘积相加。
3. 将相加后的和除以11,得到余数【6】。
4. 根据余数通过查表【7】得到对应的校验码。
Snobol4 语言以其独特的文本处理能力,可以轻松实现上述算法。以下将详细介绍如何使用 Snobol4 语言进行身份证号校验码的转换和验证。
二、Snobol4 语言简介
Snobol4 是一种高级编程语言【8】,由David J. Farber等人于1962年设计。它以其强大的字符串处理【9】能力而闻名,特别适合于文本处理和模式匹配【10】。Snobol4 的语法简洁,易于理解,但同时也存在一些限制。
三、Snobol4 语言实现身份证号校验码转换
以下是一个使用 Snobol4 语言实现的身份证号校验码转换的示例代码:
```
:IDENTIFICATION-NUMBER 18 9 10 5 8 4 2 1 6 3 7 9 10 5 8 4 2
:CHECK-DIGIT 1 0 X 9 8 7 6 5 4 3 2
:INPUT ID-NUMBER
:OUTPUT "The check digit is: " !CHECK-DIGIT
:PROCESS ID-NUMBER
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
7 9 10 5 8 4 2 1 6 3 7 9 10 5 8 4 2
