    Well, there is no strrev() function in the C standard library in the first place

    Use or replicate strlen() to find the length of the string, and then swap the corresponding nth and (length - n - 1)th chars in a loop that stops halfway through the string.

    So how much of it DO you understand. Can you read a string? Can you figure out it's length? Do you understand how to get the nth character out of a string?
