A userdefined class named Timer has a constructor that takes

A user-defined class named Timer has a constructor that takes two integer parameters to initialize hour and minute data members. Write a single C++ statement to create an object of the Timer class using dynamic memory allocation and assign it to a pointer variable named timePt r. It should call the constructor with two parameters. Use values of 10 and 20 for hour and minute respectively. Write the definition for a function named rand Ar ray that takes a single integer argument, n, and returns a dynamically allocated array of n pseudo-random integers. You may assume the pseudo-random number generator has been previously declared and seeded, (i.e. you do not need srand(time(0)) or an include.) Now write C++ statements to call the randAr ray function to construct a 100 element array, then print the array values to the display (one per line) and delete the dynamically allocated array.

Solution

#include<iostream.h>
#include<conio.h>
#include <stdlib.h>
#include <time.h>

//using namespace std;
int * randArray(int);
int * array;
class Timer   
{
int hour,minute;
public:
Timer(int x,int y)
{
hour=x;
minute=y;
}
public :
int * randArray(int n)
{
   srand((unsigned)time(0));
   for(int i=0; i<n; i++)
{
   array[i] = (rand()%100)+1;
   cout <<array[i]<<\"\ \";
}

return array;
}
public :~Timer()
{
delete array;
}
};

int main() {
   Timer * timePtr;
   int * arr;
   clrscr();
   timePtr= new Timer(10,20);
   arr=timePtr->randArray(100);
   // The Below Code is for checking that we got same return array
   //it\'s upto you if you need below code please uncoment it otherwise keep coment
/* cout<<\"Inside The Main Method\"<<endl;
   for(int i=0;i<100;i++)
   {
       cout <<arr[i]<<\"\\t\";
   } */
   delete arr;
   cout<<\"After deleting The memmory\"<<endl;
   cout<<\"!bye bye\";
   getch();
   return 0;
}
