This is my implementation of the `echo` command.

`argc > 0 && printf(" ")` is genius

Being rusty in C is, when you look at *(argv)++ and aren't sure about the operator precedence anymore..

those parentheses can’t possibly do anything, right?

oh, and also - the reason why parameters for macros-functions are often put inside parenthesis is for cases like this:

oh, right! i didn’t consider that it was the parameter of a macro and not a normal parameter! yeah, in that case it’s very sensible!

yeah
you could also do (*argv)++ and it'd yield the same results
the dereference has higher priority than increment, and is applied first

Found a bug sorry

🤣 the classic

printf $@
works for me

Add -n support and you got a perfect implementation 😃
