this is a compilation of three questions I have
I was declaring a string intended to chekc input and I called it (quotes for clarity) "in". My IDE has syntax coloring and in was colored as keyword. can someone tell me what "in" is?
in this same program I'm declaring float *<variable>
I dont know how long the array is gonna end up. in java, there is an array object called length, so array.length gives the length of the array. does something of tis sort exist in c++?
within a class, can I call methods from the class from methods within the same class? if so, do I just type the method name, as opposed to, for example, name.method()?
