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 a bad 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?
