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.

Well I am lost

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?
