2D ARRAY WITH A CLASS

i beginner on uno , programming on 1.5.6. have question how can manipulate 2d array without making 2d array(in interest of space). have tried using class, example below, upside leaves me lot more space, , code runs faster.

code: [select]


class enter{
  private:
  int right;
  int left;
  public:
  enter(){
    
  }
  enter(int y,int x){
    right=y;
    left=x;
  }
  int getright(){
    return right;
  }
  int getleft(){
   return left;
  }
  boolean check(int y,int x){
    if(right==y&&left==x){
     return true;
    }
    else{
     return false;
    }
  }
};
void setup() {
serial.begin(9600);  // put setup code here, run once:

}

void loop() {
  
    for (int p = 0; p < 10; p++) {
    for (int = 0; < 15; i++) {
      //  client.print(array[p][i]);
      //  client.print("|");
     serial.print("0");
     serial.print("|");
    }
    //client.println("<br />");
    serial.println();

  }
  serial.println("break");
  enter b(2,3);

    for (int p = 0; p < 10; p++) {
    for (int = 0; < 15; i++) {
      //  client.print(array[p][i]);
      //  client.print("|");
      
     if(b.check(p,i)){
         serial.print("4");
         serial.print("|");
     }
     else{
      serial.print("0");
      serial.print("|");
     }
     
    }
    //client.println("<br />");
    serial.println();

  }
  serial.println("done");
}



the issue comes fact cannot make variable number of these objects, have know number of "4's" needed. there anyway can work around this, va_list or need approach.

i've got news you. can't manipulate didn't make.

a variable number of objects? instances of enter class?

of course can create variable number of them. can't do, without using malloc() or new() create variable length array of them.
