Okay, I have a test tomorrow basically over strings. I am very new and in the process of learning. So our teacher gave us a pre-test and gave us all the answers if we asked for them. But I didn't and no one else asked about this one and I didn't read it but I just did and am confused on what it even means. I know it says that this place isn't something for homework but it isn't homework. I just would like to know what it means so I can do well on the test tomorrow. Now we have to write this all on paper tomorrow but I don't really understand what this is?
It says: Write a sequence of C statements that will read an integer value (position) and a string from a single line, decide if there is a valid substring of length 5 starting at the integer position just read, and print the substring if it exists.
