stuck at calling some methods in C++ to create a menu - c++

Question

I have a class ComplexesSet which represent a set of complexes numbers. I have to use this class to write a program which reads the complex numbers from keyboard and create a menu like that: press 1 to add a number in the set, press 2 to delete a number from set and press 0 to exit the program.
This is my program:
HEADER FILE
#pragma once
#include <iostream>
using namespace std;
#define DIMMAX 10;
class Complex {
int re, im;
public:
Complex() {
re = im = 0;
}
Complex(int re, int im) {
this->re = re;
this->im = im;
}
void display() {
cout << " (" << re << ", " << im << " ) ";
}
int equal(Complex c2); // check the equality between 2 complex numbers.
void read(); // reads a complex number
};
class ComplexesSet {
Complex* v; // the complex numbera array
int dim; // the maximum dimension of the array
int n; // the current number of complex numbers in the set
public:
ComplexesSet();
ComplexesSet(int d);
~ComplexesSet();
void addNumber(Complex); // add a number in set
void deleteNumber(Complex); // delete a number from set
void displaySet(); // display the set
};
METHODS FILE
#include "multime.h"
#include <iostream>
using namespace std;
int Complex::equal(Complex c2) {
if (this->re == c2.re && this->im == c2.im) {
return 1;
}
else {
return 0;
}
}
void Complex::read() {
cout << "Enter the real part: ";
cin >> this->re;
cout << "Enter the imaginary part: ";
cin >> this->im;
cout << endl;
}
ComplexesSet::ComplexesSet() {
cout << "Set of complexes numbers: ";
dim = DIMMAX;
v = new Complex[dim];
n = 0;
}
ComplexesSet::ComplexesSet(int d) {
cout << "ComplexesSet(" << d << ")";
dim = d;
v = new Complex[dim];
n = 0;
}
ComplexesSet::~ComplexesSet() {
cout << "~ComplexesSet" << endl;
if (v) {
delete[] v;
}
v = nullptr;
dim = -1;
n = -1;
}
void ComplexesSet::addNumber(Complex num) {
int ok = 0;
if (n < dim) {
for (int i = 0; i < n; i++) {
if (v[i].equal(num)) {
ok = 1;
i = n + 1;
}
}
if (ok) {
cout << "This element is already in the set.";
}
else {
v[n] = num;
n++;
}
}
else {
cout << "The set is full.";
}
}
void ComplexesSet::deleteNumber(Complex num) {
int i;
if (n != 0) {
for (i = 0; i < n; i++) {
if (v[i].equal(num)) {
break;
}
else {
cout << "This element does not exists.";
}
}
if (i < n) {
n = n - 1;
for (int j = i; j < n; j++) {
v[j] = v[j + 1];
}
}
}
else {
cout << "The set is empty.";
}
}
void ComplexesSet::displaySet() {
cout << "\n The set: {";
if (n) {
for (int i = 0; i < n; i++) {
v[i].display();
}
}
cout << "}.\n\n";
}
MAIN FILE:
#include "multime.h"
#include <iostream>
using namespace std;
int main() {
ComplexesSet m;
Complex num;
int option;
int x;
do {
cout << endl << "1 - ADD A NUMBER\n 2 - DELETE A NUMBER\n 0 - EXIT THE PROGRAM";
cin >> option;
switch (option) {
case 1:
cout << endl << "Enter the number you want to add: ";
num.read();
//? How to call addNumber method from ComplexesSet class?
// m.displaySet ?;
break;
case 2:
cout << endl << "Enter the number you want to delete: ";
num.read();
//? How to call deleteNumber method from ComplexesSet class?
// m.displaySet ?;
break;
}
} while (option >= 1 && option <= 2);
system("pause");
return 0;
}
I got stuck in the main file. How to call the addNumber and deleteNumber methods in order to add and delete a complex number from the set? Also, after pressing "1" or "2", after I read the number, I need to display the set.
