A.k.a the user enters some numbers as arguments, and the program creates an array with that many arguments. It's unclear exactly what situation you're in. If you know the array length at execution time but not at compile time, that's fine: public

"$#" I save this text field by my own. But now I have an array with some values as string target[]. I want to auto select checkboxes which has his value inside the array target[]. So if I change a value in target[], and I

I'm storing the nodes that make up the network in an array, whose dimensions are set via-tweaks at compile time (the tweaks are all const). The code worked fine until I decided to split it up into multiple files, but even with a extern declaration, it still says that "array bound is not an integer constant before ']' token". Right now, this is the set-up: In Network.h: struct Network { Node nodes

Here each of comma separated value is a String.
