If the object instance is created in a user program, then the object instance can access both the public and private members of
rewona [7]

Answer:

False

Explanation:

The private member of a class is not accessible by using the Dot notation ,however the private member are those which are not accessible inside the class they are accessible outside the class  .The public member are accessible inside the class so they are accessible by using the dot operator .

<u>Following are the example is given below in C++ Language </u>

#include<iostream>   // header file

using namespace std;  

class Rectangle

{    

   private:  

       double r; // private member  

   public:      

       double  area()  

       {     return 3.14*r*r;  

       }        

};  

int main()  

{    

  Rectangle r1;// creating the object  

   r1.r = 3.5;  

 double t= r1.area(); // calling

cout<<" Area is:"<<t;  

   return 0;  

}  

Output:

compile time error is generated

<u>The correct program to access the private member of class is given below </u>

#include<iostream>   // header file

using namespace std;  

class Rectangle

{    

   private:  

       double r; // private member  

   public:      

       double  area()  

       {    

r1=r;

double t2=3.14*r2*r2;

return(t2); // return the value  

       }        

};  

int main()  

{    

  Rectangle r1;// creating the object  

   r1.r = 1.5;  

 double t= r1.area(); // calling

cout<<" Area is:"<<t;  

   return 0;  

}  

Therefore the given statement is False

"Write code that prints: Ready! countNum ... 2 1 Start! Your code should contain a for loop. Print a newline after each number a
BartSMP [9]

Explanation:

#include <iostream.h>

#inlcude<conion.h>

void main()

{

  int count, x;

  clrscr();

  cout<<"Enter the count:";

  cin>> count;

  cout<<"Ready!\n";

  for(x=count;x>0;x--)

  {

     cout<<x<<"\n";

  }

  cout<<"Start";

  getche();

}

This is a simple program where the output is expected to be in reverse order. So we run a for loop starting from the count and decrements the counter by 1 every time when the loop runs and print the value. So to print the output in "new line" we include "\n".
