Question

The following class (long_number) represents a number of any length.

#include

#include

#include

#include

using namespace std;

class long_number

{

vector vnumber;

};

Complete the following code so that the default constructor generates the number 0.

____:

____ ()

{

vnumber. ____ ( ____ );

}

Continuing with the code on Question 4, complete the following code which implements the function print, which prints the long_number

____ print()

{

For (int ____ : ____ )

{

____ << n;

}

cout << endl;

}

If your code is correct the following code should show one (and only one) 0 on the screen.

int main() { long_number n1; n1.print(); cin.get(); return 0; }

Continuing with the code in Question 5, complete the following code which implements a constructor that turns an array of chars into a long_number.

For example, if the string is "12345", the corresponding long_number will have the following value in its fields:

vnumber = {1,2,3,4,5}

____ ( ____ input[], int_size)

{

for (int i = 0; i < ____ ; i++)

{

vnumber. ____ (( ____ )input[ ____ ] (int) ____ );

}

}

If your code is correct the following code should show 12345 on the screen.

int main() { char input1[] = "12345"; long_number n1(input1, 5); n1.print(); cin.get(); return 0; }

Continuing with the code in Question 6, complete the following code which implements the operator+ so that the operator adds to long_numbers together.

friend long_number ____ (long_number lhs, ____ long_number& rhs)

{

int carry = ____ ;

int i = ____ (lhs. ____ (), rhs. ____ ())- ____ ;

for (;i>=0;I ____)

{

int sum = lhs.vnumber[i] + rhs.vnumber[i] + carry;

lhs.vnumber[i] = sum ____ 10;

carry = sum ____ 10;

}

if (carry > 0)

{

lhs.vnumber. ____ (lhs.vnumber. ____ (), ____ );

}

____ lhs;

}

Question 8

Use the long_number from the previous part to calculate the sum of these two numbers:
