int size;

public:

GrabBag();

};

#include "GrabBag.h"

GrabBag::GrabBag() {

size = rand() % 100 + 1;

  values = new int[size]; //random array size

  for (int i = 0; i < size; i++)

  values[i] = rand()% 10 + 1 ;// random array contents  

}   

Answer 1

class GrabBag {
private:
    int* values;
    int size;
public:
    GrabBag();
    GrabBag(GrabBag &bag);
};

#include "GrabBag.h"

GrabBag::GrabBag() {
    size = rand() % 100 + 1;
    values = new int[size]; //random array size
    for (int i = 0; i < size; i++)
        values[i] = rand()% 10 + 1 ;// random array contents
}

GrabBag::GrabBag(GrabBag &bag) {
    size = bag.size;
    values = new int[size];
    for (int i = 0; i < size; i++)
        values[i] = bag.values[i];
}
