C++ Program to Print Sandglass Star Pattern

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

#include<iostream>
using namespace std;

int main()
{
	int i, j, k, rows;
     
    cout << "Enter Sandglass Star Pattern Row = ";
    cin >> rows;

    cout << "Sandglass star Pattern\n"; 

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

    for(i = rows - 1; i >= 0; i--)
    {
    	for(j = 0; j < i; j++)
		{
            cout << " ";
        }
        for(k = i; k <= rows - 1; k++)
        {
            cout << "* ";
        }
        cout << "\n";
    }	
 	return 0;
}
C++ program to Print Sandglass Star Pattern

This C++ example prints the sandglass pattern of a given character using a while loop.

#include<iostream>
using namespace std;

int main()
{
	int i = 0, j, k, rows;
    char ch;
     
    cout << "Enter Sandglass Star Pattern Row = ";
    cin >> rows;

    cout << "Enter Symbol to Print in Sandglass Pattern = ";
    cin >> ch;

    cout << "Sandglass Pattern of Given Symbol\n"; 

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

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