字符串中，中文/英文/数字字符的自动识别(50分)

For example :'122229，南京东路，Hello ,world'
this sentence is read in one string,but how can I recognize which is Chinese code or
English code,and so on.

Thank you firstly.

It's very easy.You can use ascii(string).
step1:read this string char by char
step2:judge it(0-9 in ascii is 48-57)
a-Z(69 ... I forget,you can test it)
The ascii of chinese char is bigger than 120.
step:do your things

Most of above is correct.
Good Luck!
