Having trouble with strings..(C)

Question

So, user types in a string and I store it in an array..
Ex. char arr[20]; // input : "tuna"
I check for the end of string using eof... can't find the end. Used the '\0' pointer still doesn't work since I already allocated memory for the string.
How do I get the result -> length = 4?
