C++ OOP program to print stars in a Rhombus pattern using classes.
#include<iostream> // start
using namespace std; //libraries
class projectsinventory_DotCom_Rhombus // creating class
{
private: //private variables
int r,sp; //declare int type variables
public: //use for showing data anywhere in this program
void disp() //create function
{
for(r=1;r<=4;r++) //loop for displaying the number of rows
{

{
cout<<" "; // cout for printing space
}
if(r==1||r==4) //condition for first or last row
{

{

}
}

{
