Printing Star by rows in C++

Printing Star by rows in C++ using inline functions

Here, I am sharing you a C++ program for printing the star by rows in C++ using inline functions.

#include<iostream>
using namespace std;
class patr
{
	protected :
		int i,j,k,n;
	public :
		fun();
};
inline patr::fun()
{

		cout<<"input No of rows : ";
		cin>>n;
		for(j=1 ; j<=n ; j++)
		{
			for(i=j ; i<n ; i++)
			{
				cout<<" ";
			}
			for(i=1 ; i<=j ; i++)
			{
				cout<<"*";
			}
			cout<<"\n";
		}
}
int main()
{
	patr a;
	a.fun();
}

Printing Star by rows in C++ using friend functions

Here, I am sharing with you a C++ program for printing the star by rows in C++ using the friend functions.

#include<iostream>
using namespace std;
class pat
{
	protected :
		int i,j,r;
	public :
		input()
		{
			cout<<"input No of rows : ";
			cin>>r;
		}
		friend int show(pat);
		
};
int show(pat a)
{
	for(a.j=1 ; a.j<=a.r ; a.j++)
	{
		for(a.i=a.j ; a.i<a.r ; a.i++)
		{
			cout<<" ";
		}
		for(a.i=1 ; a.i<=a.j ; a.i++)
		{
			cout<<"*";
		}
		cout<<"\n";
	}
}
int main()
{
	pat a;
	a.input();
	show(a);
 }

Printing Star by rows in C++ using constructor overloading

Here, I am sharing with you a C++ program for printing the star by rows in C++ by using constructor overloading.

#include<iostream>
using namespace std;
class construct
{
	protected :
		int i,j,k,n;
	public :
		construct(int n)
		{
			for(j=1 ; j<=n ; j++)
			{
				for(i=j ; i<n ; i++)
				{
					cout<<" ";
				}
				for(i=1 ; i<=j ; i++)
				{
					cout<<"*";
				}
				cout<<"\n";
			}
		}
		construct(int two,int three)
		{
			cout<<"\n\n1st patern is \n\n";
			for(j=1 ; j<=two ; j++)
			{
				for(i=j ; i<two ; i++)
				{
					cout<<" ";
				}
				for(i=1 ; i<=j ; i++)
				{
					cout<<"*";
				}
				cout<<"\n";
			}
			cout<<"\n\n2nd patern is \n\n";
			for(j=1 ; j<=three ; j++)
			{
				for(i=j ; i<three ; i++)
				{
					cout<<" ";
				}
				for(i=1 ; i<=j ; i++)
				{
					cout<<"*";
				}
				cout<<"\n";
			}
			
		}
};
int main()
{
	cout<<"\t\t\tThis Program Demonstrate The Single and";
	cout<<"multiple paramter Constructor\n\n\n";
	int option;
	cout<<"Enter 1 of Single parameter constructor \n";
	cout<<"\nEnter 2 For Multiple Paramter constucor \n";
	cout<<"\nEnter 1 or 2 : ";
	cin>>option;
	system("cls");	//this function is to clear the screen
	if(option ==1)
	{
		cout<<"\t\t\t-------You Have Slected Single Paramater";
		cout<<"Constructor-------\n\n";
		int n;
		cout<<"Enter Number of rows : ";
		cin>>n;
		construct a(n);
	}
	else if(option==2)
	{
		cout<<"\t\t\t-------You Have slected Multiple Paramater ";
		cout<<"Constructor-------\n\n";
		int two,three;
		cout<<"\n\nEnter Number of rows for 1st patern : ";
		cin>>two;
		cout<<"\n\nEnter Number of rows for 2nd patern : ";
		cin>>three;
		construct a(two, three);
	}
	else
	{
		cout<<"Your Input in Wrong try Agin \n\n\n";
	}

Printing Star by rows in C++ using the constructor

Here, I am sharing with you a C++ program for printing the star by rows in C++ by using the constructor.

		pat()
		{
			cout<<"input No of rows : ";

			{
				for(i=j ; i<r ; i++)
				{
					cout<<" ";
				}
				for(i=1 ; i<=j ; i++)
