Question

I want to manipulate an array of integers in a function, but I am not sure if I should use the address prefix or the pointer prefix:

void shuffle(int *deck[]){  
    //statements
}

or

void shuffle(int &deck[]){  
    //statements
}

Further, when I directly want to manipulate the values of the array, I’m not sure if I should use (within the function)

*deck[4] = 34

or something else.

Any clarification is appreciated.

Answer 1

Neither.

Since arrays can be passed by reference only, you don’t need to do tricks, just pass a pointer and dereference it. (That syntax involving the & in your 2nd function is not valid, anyway). So:

void shuffle(int arr[])
{
    arr[0] = 1337;
}

or

void shuffle(int *arr)
{
}

etc. And you can pass it like this:

int deck[52];
shuffle(deck);
