C PROGRAMMING

Implement a function that copies a string by reversing its characters and converting all upper case letters to lower case.

This function reverses its first null$-$terminated string argument str into the string copy while converting all upper case characters to lower case characters. For example, if

str$[]=$ "HeLLo"

After calling the function, copy would be

copy$[]=$ "olleh"

The function should make copy a valid C string by properly terminating it with null termination character.

Hint

stdlib provides useful character handling functions in ctype.h$.$

Important

copy can be assumed to have enough space for copying the str$.$ You do not need to allocate memory for it$.$

$*$ whether your function implementation is correct.

$//$ You can write your own test code here.
