Passing an STL queue as parameter to another function in C++

I am having some issues passing a queue as a parameter to a function in C++ I have an STL queue defined queue<int> example[100];

I have a function defined void calculateSum(queue<int> &example, int size){}

I am trying to pass the queue to this function by writing calculateSum(example, 100) but I keep getting an error saying [cquery] no matching function for call to 'minimumDistance'

What should I do? Any feedback would be helpful

queue<int> example[100]; will create an array (named example) of queues. Your function, void calculateSum(queue<int> &example, int size), accepts a reference to a single queue of ints (not an array of queues).

Assuming you do in fact want an array of queues, and you do want that function to accept a reference only to a single queue, you must choose one of the queues from your array to pass into it. For example, you could do calculateSum(example[0], 123); to pass in the first queue in your array.

Your declaration queue<int> example[100]; makes an array of 100 queues.

What you probably want is just queue<int> example; and then let it grow as you add elements.
