String Parsing

[super.mina]

The user enters the following :

" x+sin(x)-pow(x,2)+5log(x)"

How can I make parsing for a statement like that .

Look at the string character by character.

I did . but I have no Idea .

I have just finished a Course in C and this is the final project .

Can you guide me to some teaching books or helpful websites

There are a variety of ways to do this; see these links for some ideas to get you started.

Basically this problem is identifying "strings of interest" log / sin / cos / (x)
You use the strtok function to identify the start and end of these kind of strings

strtok modifies its target string. This is abad thing if you want to search multiple times over several delimiters.

In almost all cases strtok is the wrong tool to use when parsing input.

Describe why. Lot's of answers here, and since you finished the course, you must know how to work with arrays. What's your real problem?
