Answer 1

Nice code man!
There are three reasons why you don't get any output.
1- You should declare reverse as "char *" and not only "char". You are in fact returning a pointer to char (that is, a string)
2- In the first "for cycle" you compare a char with "\0", but if you write "\0", this is a string. I you want to treat \0 as a char you should write '\0' instead.
3- When you write "Hello", this is a "const char*" and you can't modify it. In order to use your function you have to declare a separate variable and pass it to your function:
...
char s[] = "Hello";
printf("%s", reverse(s));
...

Hope this helped!
