Question

I have this code

enum type {NOTHING, SOMETHING, SOMETHINGELSE}
type *x;

At the moment I use x[765] == SOMETHING for example, How would I store other values for example

x[765] == SOMETHINGELSE;
x[765].position == 43.5;
x[765].somevar == 12;

I will apologize for my poor wording within my question im just starting out in C++, I know what I want i’m just not to sure on how to ask it.

Thanks.

It looks as if you’re looking for a way to structure ‘knowledge’; this is done with a struct or a class:

#include <vector>

struct Info {
   enum thingness { nothing, something };

   // 'member' variables
   thingness howMuch;
   int a_counter;
   float position;
};

int main(){
  Info object;
  object.howMuch=Info::something;
  object.a_counter=1;
  object.position=5.4;

You can group these kinds of objects into a container – typically an std::vector:

  // a container of InterestingValues
  std::vector<Info> container(300);

  container[299].howMuch=Info::nothing;
  container[299].a_counter=4;
  container[299].position = 3.3;

  // or assign rightaway:
  container[2] = object;
}
