C++ Program to Print W Star Pattern

Write a C++ program to print W star pattern using for loop. In this C++ example, printingSpaces iterate from 0 to rows and prints the empty spaces and printingStars will print the stars. 

#include<iostream>
using namespace std;

void printingStars(int rows)
{
	for (int i = 0; i < rows; ++i)
	{
		cout << "*";
	}
}
void printingSpaces(int rows)
{
	for (int i = 0; i < rows; ++i)
	{
		cout << " ";
	}
}

int main()
{
	int rows;

	cout << "Enter W Shape Star Pattern Rows = ";
	cin >> rows;

	cout << "Printing W Shape Pattern\n";
	for (int i = 0; i < rows; i++)
	{
		printingStars(i + 1);
		printingSpaces(rows - i - 1);
		printingStars(rows - i + 1);
		printingSpaces(2 * i);
		printingStars(rows - i);
		printingSpaces(rows - i - 1);
		printingStars(i + 1);
		cout << "\n";
	}
}
C++ Program to Print W Star Pattern

This C++ program prints the alphabetical W pattern of stars using a while loop.

#include<iostream>
using namespace std;

void printingStars(int rows)
{
	int i = 0;
	while (i < rows)
	{
		cout << "*";
		++i;
	}
}
void printingSpaces(int rows)
{
	int i = 0;
	while (i < rows)
	{
		cout << " ";
		++i;
	}
}

int main()
{
	int rows;

	cout << "Enter W Shape Star Pattern Rows = ";
	cin >> rows;

	cout << "Printing W Shape Pattern\n";
	int i = 0;
	while (i < rows)
	{
		printingStars(i + 1);
		printingSpaces(rows - i - 1);
		printingStars(rows - i + 1);
		printingSpaces(2 * i);
		printingStars(rows - i);
		printingSpaces(rows - i - 1);
		printingStars(i + 1);
		cout << "\n";
		i++;
	}
}
Enter W Shape Star Pattern Rows = 13

In this C++ example, the printingStars function allows entering any character and prints the W pattern of a given character.

#include<iostream>
using namespace std;

void printingStars(int rows, char ch)
{
	for (int i = 0; i < rows; ++i)
	{
		cout <<  ch;
	}
}

void printingSpaces(int rows)
{
	for (int i = 0; i < rows; ++i)
	{
		cout << " ";
	}
}

int main()
{
	int rows;
	char ch;

	cout << "Enter Character for W Pattern = ";
	cin >> ch;

	cout << "Enter W Shape Star Pattern Rows = ";
	cin >> rows;

	cout << "Printing W Shape Pattern\n";
	for (int i = 0; i < rows; i++)
	{
		printingStars(i + 1, ch);
		printingSpaces(rows - i - 1);
		printingStars(rows - i + 1, ch);
		printingSpaces(2 * i);
		printingStars(rows - i, ch);
		printingSpaces(rows - i - 1);
		printingStars(i + 1, ch);
		cout << "\n";
	}
}
Enter Character for W Pattern = $
Enter W Shape Star Pattern Rows = 16
