If i have a function, say CreateArray() that creates an array but i want to return the array to use it in the part of a project that calls the function how would i store the returned array? i tried: Array[index]=CreateArray(); CreateArray() { blah blah return NewArray[index]; } and also NewArray=CreateArray; CreateArray() { blah return Array; } The only way i have been able to do this is if NewArray is a global variable and CreateArray() changes it. Is there a better way to do it? Thanks for any help "People spend too much time thinking about the past, whatever else it is, its gone"-Mel Gibson, Man Without A Face

void main()
{
    int *piArray;
 
    // Create an array with 5 elements

    piArray = CreateArray(5);
 
    // Display the array elements

    for (int i = 0; i < 5; i++)
    {
        cout << piArray<i> << endl;
    }
 
    delete [] piArray;
 
}


int* CreateArray(int numElements)
{
    int *piTempArray;
 
    // Create the new array

    piTempArray = new int[numElements];
 
    // Fill it with test values

    for (int i = 0; i < numElements; i++)
    {
        piTempArray<i> = i;
    }
 
    return piTempArray;
}

Good?

You used the letter "i" as the index of the array. The source section translates it to < "i" > (less the quotes) so it doesn''t italicize the rest of the source block.
