C++ Program to Print Downward Triangle Star Pattern

Write a C++ program to print the downward triangle star pattern using for loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows;
     
    cout << "Enter Downward Triangle Star Pattern Rows = ";
    cin >> rows;

    cout << "Downward Triangle Star Pattern\n"; 

    for(i = rows - 1; i >= 0; i--)
    {
    	for(j = 0; j <= i; j++)
		{
            cout << "* ";
        }
        cout << "\n";
    }		
 	return 0;
}

This cpp example program displays the downward triangle pattern of a given symbol using a while loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows;
    char ch;

    cout << "Enter Rows = ";
    cin >> rows;

    cout << "Enter Symbol for Downward Triangle Star Pat = ";
    cin >> ch;

    cout << "Downward Triangle Pattern of Given Symbol\n"; 

    i = rows - 1;
    while( i >= 0)
    {
        j = 0; 
    	while(j <= i)
		{
            cout << ch << " ";
            j++;
        }
        cout << "\n";
        i--;
    }		
 	return 0;
}

Enter Rows = 15
Enter Symbol for Downward Triangle Star Pat = @
Downward Triangle Pattern of Given Symbol
