C++ Program to Print Inverted Star Pyramid

Write a C++ Program to Print Inverted Star Pyramid with an example. This C++ program allows us to enter the rows and the symbol to print in the inverted pyramid pattern. Next, the nested for loops will iterate between total rows and 1 to print the * (or given symbol). Here, if k != (2 * i – 1) condition is true, print * otherwise, print empty space.

#include<iostream>
using namespace std;

int main()
{
	int i, j, k, rows;
	char ch;
	
	cout << "\nPlease Enter Inverted Pyramid Star Pattern Rows    =  ";
	cin >> rows;
	
	cout << "\nPlease Enter Any Symbol to Print  =  ";
	cin >> ch;	
		
	cout << "\n-----Inverted Pyramid Star Pattern-----\n";
	for ( i = rows ; i >= 1; i-- )  
	{
		for ( j = 0 ; j <= rows - i; j++ ) 
		{
      		cout << " ";   	
		}
			
		for(k = 0; k != (2 * i - 1); k++)
		{
			cout << ch;
			
		}
		cout << "\n";
	}

 	return 0;
}

C++ Program to Print Inverted Star Pyramid using a While Loop

#include<iostream>
using namespace std;

int main()
{
	int i, j, k, rows;
	char ch;
	
	cout << "\nPlease Enter Inverted Pyramid Star Pattern Rows    =  ";
	cin >> rows;
	
	cout << "\nPlease Enter Any Symbol to Print  =  ";
	cin >> ch;	
		
	cout << "\n-----Inverted Pyramid Star Pattern-----\n";
	i = rows ; 
	while(i >= 1 )  
	{
		j = 0 ; 
		while( j <= rows - i) 
		{
      		cout << " ";
      		j++ ;
		}
		
		k = 0;
		while (k != (2 * i - 1))
		{
			cout << ch;
			k++;
		}
		cout << "\n";
		i--;
	}

 	return 0;
}

Output

Please Enter Inverted Pyramid Star Pattern Rows    =  9

Please Enter Any Symbol to Print  =  #
