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

Tokenize the string. The results that contain a single character is a char (according to your statement), the elements that are digits must be integers, right?, then the rest must be strings.

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.
