	int size;
	cin >> size;
	ar = new char[size];
	srand(time(NULL));
	for( int i = 0; i < size; i++){
		ar[i] = (char)rand() % 40;
	}

		cout << &ar[i] << " \n";
		cout << *(&ar[i]) << endl;
	}

i think it might be line 25. you should probably just make it *(ar[i]), otherwise i believe the other way it tries to dereference the address. i suggest also taking a look at std::array and the std smart pointers.

Line 18: You're generating a random character from 0 - 39. The first 32 values are control characters.

Which ASCII characters are you trying to generate?

Line 24: You're going to output the address of a character. Is that what you intended?
