Answer 1

header file test.h
==================

#ifndef Test_H_
#define Test_H_

#include <iostream>

using namespace std;

class Test {
private:
int id;
static int count;

public:
static int const MAX = 99;
Test(); // Auto-generated default constructor prototype.
~Test(); // Auto-generated default destructor prototype.
static void showInfo();
int getId();
};

#endif //__Test_H_

Test.cpp file
==================

#include "Test.h"

int Test::count = 0;

Test::Test() {
id = ++count;
}

Test::~Test() {

}

void Test::showInfo() {
cout << count << endl;
}

int Test::getId() {
return id;
}

main.cpp
===============

#include <iostream>
#include "Test.h"

using namespace std;

int main() {

cout << Test::MAX << endl;
Test::showInfo();

Test test1;
cout << "Object 1 ID: " << test1.getId() << endl;
Test test2;
cout << "Object 2 ID: " << test2.getId() << endl;
Test test3;
cout << "Object 3 ID: " << test3.getId() << endl;
Test test4;
cout << "Object 4 ID: " << test4.getId() << endl;

Test::showInfo();

return 0;
}
