reverse string without using strrev() function

any idea to reverse string without using strrev() function in C?
*Just only use stdio.h to complete scoure code

Thank you for your idea ^^

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.

Erm,can give some example?i didn't understand what u try to explain. XD

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?
