Im having a hard time figuring out how you call a base class constructor from the dervied class.

Code:
//Setting instance variables in base class constructor
player(int num, char *player_name)
{
            number = num;
	name = new char[20];
            strcpy(name, player_name);
}

//Constructor in derived class
hplayer(int number, double salary = 500000.00, char *name = "Bill");

//scoped into class
hplayer::hplayer(int number, double salary, char *name):call here()
{
	//set instance variable
            sal = salary
}
The problem is I dont know how to call the base class constructor

Thanks
