fuctions with void parameters

Hello I am a novice programmer with a question about these weird functions with void in the () brackets for example DataType DeleteFront(void); I would like a good explanation from a programmer because i have searched for the answer for a while. I do not know why they are there and what can be used to pass to them.

Here is a list of few examples:

// list modification methods 
    void Insert(const DataType& item);
    void Delete(const DataType& item);
    DataType DeleteFront(void);
    void ClearList(void);  //<<==== Like this one for instance
};

// Class Definition: 

// constructor. set size to 0 
SeqList::SeqList(void) : size(0)
{}

// return number of elements in list 
int SeqList::ListSize(void) const
{
    return size;
}

// tests for an empty list 
int SeqList::ListEmpty(void) const
{
    return size == 0;
}

// clears list by setting size to 0 
void SeqList::ClearList(void)
{
    size = 0;
}
