Simple function I wrote to share. Enjoy

Its sad none of your posts get any comments when they are pretty HQ. Keep it up!

Too bad I don't know any C.
I should probably pick up a book and a project.

str[0] is str

basically the brackets are just adding the number to the first pointer value..

like
str[0] is str+0
str[1] is str+1
str[2] is str+2
etc

Yeh I'm not sure why you dereferenced str[0] and not just str.

In the end it doesn't truthfully matter. I use &str[0] as preference for readability, since &str isn't the same as str in this context. With &str[0] I know it's a c-style string when I first look at the code and I can see that I'm pointing to the first char in the sequence before the null terminator, and not just some other type's value (implying a non-pointer), where str by itself, disregarding the variable name, may not be as obvious without looking back at the declaration or utilizing intellisense. I use a text editor to compile my C code, not any fancy IDE... The compiler output doesn't differentiate between &str[0] and str, so it would be the same as arguing what kind of naming convention is used... As long as there is consistency it doesn't matter. :smile:

You'd either have to have been given a compiler error/warning where the pointer is mis-used, or, you'd have to look at the declaration or where it's being used to see that it's a pointer if it is not obvious (unless hungarian notation was used).
