Thanks for the help guys!

Given the program below;

// Array Allocator
#include <iostream>
using namespace std;

// Function Prototype
int* arrayAllocator(int);

int main()
{

   int numElements;  // To hold the number of elements to allocate
   int *pointer;           // A pointer to the array
   int i;                       // A loop counter

   // Get the array size.
   cout << " Enter an array size: " << endl;
   cin >> numElements;
   
   // Allocate the array.
   pointer = arrayAllocator(numElements);

   // Fill the array with values.
   for (i = 0; i < numElements; i++)
      pointer[i] = i;

   // Display the values.
   cout << "Here are the values in the array: ";
   for (i = 0; i < numElements; i++)
      cout << "Element " << i << " has the value " << *(pointer + i) << endl;

   // Deallocate the array.
   delete [] pointer;
   pointer = 0;
   return 0;

}

Write a function that dynamically allocates an array of integers. The function should accept an integer argument indicating the number of elements to allocate. The function should return a pointer to the array.

Thanks for the help guys! Given the program below; // Array Allocator #include using namespace std; // Function Prototype int* arrayAllocator(int); int main() { int numElements; // To hold the number of elements to allocate int *pointer; // A pointer to the array int i; // A loop counter // Get the array size. cout

Explanation / Answer

// Array Allocator
#include <iostream>
using namespace std;
// Function Prototype
int* arrayAllocator(int numElements)
{
int *pointer_to_array = new int[numElements];
return pointer_to_array;
}
int main()
{
int numElements; // To hold the number of elements to allocate
int *pointer; // A pointer to the array
int i; // A loop counter
// Get the array size.
cout << " Enter an array size: " << endl;
cin >> numElements;
// Allocate the array.
pointer = arrayAllocator(numElements);
// Fill the array with values.
for (i = 0; i < numElements; i++)
pointer[i] = i;
// Display the values.
cout << "Here are the values in the array: ";
for (i = 0; i < numElements; i++)
cout << "Element " << i << " has the value " << *(pointer + i) << endl;
// Deallocate the array.
delete [] pointer;
pointer = 0;
return 0;
}
