Need help with assignment

[icecody12]

I need help with the functions: is_duplicate and remove_all to work for my assignemt. Here is the code, been trying to get it to work for the past two hours. Any help would be nice

<code>
#include <iostream>
using std::cout; using std::cin; using std::endl;

class MyList
{
private:
const static int INC = 10;
const static int DCAP = 20;
int *a;
int csz;
int cap;
bool move();

public:
MyList();
MyList(int);
//destructor
~MyList();
bool add(int);
// bool remove(int);
bool empty();
bool clt();
bool full();
void erase();
int is_duplicate(int v);
bool remove_all();
bool present(int);
void display();
};

MyList::~MyList()
{
cout << "I'm being destroyed!!" << endl;
delete[] a;
}

bool MyList::move()
{
// cout << "Moving to a new array..." << endl;
int *p = new int[csz + INC];
for (int i = 0; i < csz; ++i)
p[i] = a[i];
delete[] a;
a = p;
cap = csz + INC;
// cout << "Done!" << endl;
return true;
}

bool MyList::clt()
{
cout << "Please enter the size of array:";
int size;
cin >> size;
csz=size;

for (int i=0; i <csz; i++)
{
cin >> a[i];
}
}


void MyList::display()
{
cout << "Capacity: " << cap << endl;
cout << "Current size: " << csz << endl;
cout << "Contents: " << endl;
for (int i = 0; i < csz; ++i)
cout << a[i] << " ";
cout << endl;
}

MyList::MyList()
{
//cout << "Default constructor is called." << endl;
csz = 0;
a = new int[DCAP];
if (a == nullptr)
cout << "failed!!" << endl;
cap = DCAP;
}

MyList::MyList(int ucap)
{
//cout << "Parameterized constructor is called." << endl;
csz = 0;
if (ucap <= 0)
cap = DCAP;
else
cap = ucap;
a = new int[cap];
}

bool MyList::full()
{
if (csz == cap)
return true;
else
return false;
}

bool MyList::add(int v)
{
if (full())
move();
a[csz] = v;
++csz;
return true;
}

bool MyList::empty()
{
if (csz == 0)
return true;
else
return false;
}

bool MyList::present(int v)
{
for (int i = 0; i < csz; ++i)
if (a[i] == v)
return true;
return false;
}


bool MyList::remove_all()
{
int number;
cin >> number;
cout << "Please enter duplicates" << number << "that are found";
for (int i= 0; i= csz; i++)
{
if (number == a[i])
{
for (int n= i; n < csz-1; ++n)
{
a[n]=a[i+1];
}
csz= csz-1;
}
}

}


void MyList::erase()
{

cout << "Array being erased now fucker";
for (int i =0; i < csz; i++)
{
a[i]=0;
}


}
int MyList::is_duplicate(int v)
{
int count = 0;
for(int i=0; i< csz ; i++)
{
int v;
if(a[i]==v)
{
count++;
}
}
return count;
}



int main()
{
MyList l1;
l1.clt();
//memory all MyListocated dynamicall
l1.display();
cout << "lets find the duplicates:";
l1.is_duplicate(int v);
cout <<"would you like to remove duplicates? Put 1 for yes, 2 for nah:";
int input;
cin >> input;
if (input == 1)
{
l1.remove_all();
}
else if (input == 2)
{
cout << "Okay have fun!:";
l1.erase();
}

l1.display();


}

You used the wrong style of code tags.
We use [ ] here, not <>

Perhaps:

#include <iostream>

public:
	MyList();

	~MyList();

	bool add(int);
	bool empty();
	bool clt();
	bool full();
	void erase();
	int is_duplicate(int v);
	bool remove_all(int v);
	bool present(int);
	void display();
};

MyList::~MyList()

	for (int i = 0; i < csz; ++i)

}

	for (int i = 0; i < csz; ++i)

}
