Question

In C I want a function like this:

bool RemoveFirstIndex(char* inArray[])

which goes in and takes out the very first element in that array.

e.g.

inArray = "Hello\o", "How\o", "Are\o"
RemoveFirstIndex(inArray)
inArray = "How\o", "Are\o"

Not sure how to go about it.

I get the idea that I would have to create a new array of inSize – 1, and just fill it with everything except index 0.
But if I do that, does the function need to return a new char*[]? Isnt that a bit wasteful?

Thank you.

Answer 1

Why remove the first element or create a new array?

Just can just increment your pointer so it points to the next item in the array.

char **newArray = inArray + 1;

newArray is valid as long as inArray is.
