Anything similar to charAt() in C?, Finding characters

I need to find the third element of each word in an array of strings, eg {"catfish", "doggie", "random"}, where the strings are some random words. How do I get the third element of the second word for example if I don't know what the second word actually is?

Yes, that's right, you can find a character in a single string this way, but when you have a pointer array, eg: CODE char** an_array_of_strings[3]={"balloon", "whatever", "isnext"}; -- how do you find out which is the third character of the second word? In "whatever" it is an 'a' but what if you don't know the words? I've learned java before but now I'm a bit confused with pointers in C. I just think if I should save each word in a different array first and then find the third character of each word or there is any better way to do that. With pointers anyhow? (I just don't understand these pointers very well yet.)

(Something like "Pointers for Dummies" perhaps? ) I really would like to understand how to use them. I'm a total beginner in C and those pointers are confusing... Oy!
