debug the following code. the program should return 1.5. the program will have an object 'i' that contains a counter and an array of numbers. in the end, it will call avg() to sum the numbers in the array and divide by counter and return the result. please use c++.

#include

using std::cout, std::endl;

struct Number {

int x;

Number () : x() {}

Number (int _x) : x(_x) {}

};

class res {

private:

int counter; //use to count the number of nums

Number** nums; //stores an array of nums

double *avg; //stores average

public:

res (int _counter) { //declare the amount of number we'll use

counter = _counter;

nums = new Number*[counter];

}

~res () {

for (int i=0; i<=counter;i++) {

delete[] nums[i];

}

}

void add_all_nums (Number *pt /*unsized array */) {

for (int i = 0; i <= counter; i++) {

nums[i]=new Number();

memcpy(nums[i], &pt[i%counter], sizeof(Number));

}

}

double* avg () {

int sum;

for (int i = 0; i <= counter; i++) {

sum+=nums[i]->x;

}

avg = new double(sum/counter);

return avg;

}

};

int main () {

Number i1;

i1.x = 0;

Number i2;

i2.x=1;

Number i3;

i3.x = 2;

//fix this code

Number pts[3] = {i1, i2, i3};

res i = res(3); //declare res i with a counter of 3

i.add_all_nums(pts); // add numbers to the i object's array

cout<<"average = "<

}
