根据变量类型分隔线的方法 [英] the way to separate a line according to variable types

问题描述

hi
我期待找到分离整数，字符串和字符的最佳解决方案。



char line [100];

得到（行）;



用户输入''有1个房间和90个人''

然后程序分类如下并打印它们

整数= 1,90

字符串=有空间和人''

char = a



我认为使用ascii代码可以做到这一点，但它仍然令人困惑。

如何解决它？需要你的建议

hi I''m looking forward to finding the best solution for separation of integer,string and char.

char line[100];
gets(line);

user input ''there is a 1 room and 90 people''
then the program classifies like below and print them
integer = 1, 90
string = there is room and people''
char = a

I think it''s possible to do it with using ascii code, but it has been still confusing.
How to solve it? need your advice

推荐答案

看起来你想要一种解析器或至少一个 lexer 。您可以使用 Flex 和 Bison 进行此类操作，这些免费且易于使用Google查找。



是的，所有字符当然都存储为计算机中的数字，从数字到字符的最重要的映射之一是ASCII。

It looks like you want a form of parser or at least a lexer. You can do this sort of thing with Flex and Bison which are free and easy to find with Google.

Yes all characters are of course stored as numbers in a computer and one of the most important mappings from numbers to characters is ASCII.
