Question

I need to complete this project. Here are the instructions below and the code I must use as a baseline is below the instructions. Can I get help in completing this assignment:

Using the addresses.cpp file as a base, do the following:

·        Create a pass-by-value function that takes an integer as an input. Pass in the integer a and, in the function, print out the passed in variable's address.

·        Create a pass-by-pointer function that takes a pointer to an integer. Pass in a's address, and print the address stored in the pointer in that function.

·        Create a pass-by-reference function that takes a reference to an integer. Pass in the integer a and, in the function, print out the passed in reference's address.

Turn in your C++. In the turn in notes, discuss whether the addresses are the same or different than a's address.

/* Print some addresses in memory */

#include <iostream>

using std::cout;
using std::endl;

int main()
{
// Create some variables and print where they are in memory
int a, b;

int items[6];

int moreitems[2][3];

cout << "Location of ints a,b: "
<< static_cast<void*>(&a)
<< " "
<< static_cast<void*>(&b)
<< endl;

cout << "Location of int array items: " << static_cast<void*>(items)
<< endl;

cout << "Location of int array moreitems"
<< static_cast<void*>(moreitems)
<< endl;

return 0;
}

Explanation / Answer

#include<iostream>

void passByValue(int a)
{
// The address of a should be different than address of a in main
cout <<"Address of a passed as value is: "<<&a<<endl;
}
void passByPointer(int *a)
{
// The address in pointer should be same as address of a in main
cout <<"Address of a passed as pointer is: "<<a<<endl;
}
void passByReference(int &a)
{
// The address of a should be same as address of a in main
cout <<"Address of a passed as reference is: "<<&a<<endl;
}

int main()
{
    // Create some variables and print where they are in memory
    int a, b;

    int items[6];

    int moreitems[2][3];

a=10;


    cout << "Location of ints a,b: "
         << static_cast<void*>(&a)
         << " "
         << static_cast<void*>(&b)
         << endl;

    cout << "Location of int array items: " << static_cast<void*>(items)
         << endl;

    cout << "Location of int array moreitems"
         << static_cast<void*>(moreitems)
         << endl;
       
    passByValue(a);
passByPointer(&a);
passByReference(a);

    return 0;
}
