C++ concatenate two int arrays into one larger array

Question

Is there a way to take two int arrays in C++

int * arr1;
int * arr2;
//pretend that in the lines below, we fill these two arrays with different
//int values
         


        

Answer 1

for (int i = 0; i< arraySize * 2; i++)
{
    if (i < aSize)
    {
        *(array3 + i) = *(array1 + i);
    }
    else if (i >= arraySize)
    {
        *(array3 + i) = *(array2 + (i - arraySize));
    }

}

This might help you along, it doesn't require vectors. I had a similar problem in my programming class. I hope this helps, it was required that I used pointer arithmetic. This assumes that array1 and array2 are initialized dynamically to the size "aSize"
