INSTRUCTIONS ARE: Write a function that accepts an int array and the array’s size as arguments.
1. The function should create a new array that is twice the size of the argument array.
2. The function should copy the contents of the argument array to the new array, and initialize the unused elements of the second array with 0.
3. The function should return a pointer to the new array.

Demonstrate the function by using it in a main program that reads an integer N (that is not more than 50) from standard input and then reads N integers from a file named data into an array.

The program then passes the array to your array expander function, and prints the values of the new expanded array on standard output, one value per line.

You may assume that the file data has at least N values. There are no prompts for the integer and no labels for the expanded reversed array that is printed out. If the integer read in from standard input exceeds 50 or is less than 0 the program terminates silently.

HERES MY CODE:

#include
#include
#include
using namespace std;

int * expand (int [], int);

int main ()
{
int size;

cout > size;

if (size > 50)
return 0;
else if (size > arr[i];
}

for (int i = 0; i < size*2; i++)
{
cout << *(expand (arr, size)+i);
}

return 0;
}

int * expand (int arr[], int size)
{
int * ptr = new int [size*2];

for (int i = 0; i {
*(ptr+i) = arr[i];
}
for (int i = size+1; i {
*(ptr+i) = 0;
}

return ptr;
}

WHAT IS WRONG AND WHAT SHOULD I DO/CHANGE?

answer is:

a). backstage view

explanation:

backstage view is the area where files and data about them is managed— creating, saving, printing, sending to others, inspecting for hidden metadata or personal information, and setting options. so in this way we can add many things to our document swiftly.

i hope you get the idea.
