you see we don't do homework but i"ll explain a little that you"ll understand the idea

class structure:

class name_of_the_class{
private:
//here goes the private data members
//and the private methods mostlly data
//members
public:
//here goes the public data members
//and the public methods mostlly methods
//and the c'tors and the d'tors
};

now the idea of the c'tor is to updata the class data members with data at the creation of the class like
class myclass{
private:
int x;
public:
myclass(int x1){
x=x1;
}
then in main
myclass class1(1);
//it will create a class named class1 //type of myclass when the x paramter
//will be 1 <x=1>

//the d'tor used to free memory when
//class is distoried it used to free
//dynamic allocated memroy using the
//funcs delete or delete[]

i hope you got the idea now you"ll have to do the rest by yourself

class myclass
{
public:
void myclass();
void ~myclass();
}

myclass::myclass()
{
//code for constructor goes here
}

myclass::~myclass()
{
//code for destructor goes here
}

constuctors are called whenever someone makes a variable of your class type. Destructors are called when it is destroyed.
Hope this helps.
