C++ Program To Print Diamond Pattern Using *

Here our task is to print the required pattern without actually writing it manually. We will see how to do this for a diamond pattern. The simplest case will be to make the pattern using * only.

Following is the program to print diamond using *.

#include<iostream>
using namespace std;
int main()
{
	int i, j, k, rows;
 
 cout << "Enter Diamond Star Pattern Row = ";
 cin >> rows;
 cout << "Diamond Star Pattern\n"; 
 for(i = 1; i <= rows; i++)
 {
 	for(j = 1; j <= rows - i; j++)
		{
 cout << " ";
 }
 for(k = 1; k <= i * 2 - 1; k++)
 {
 cout << "*";
 }
 cout << "\n";
 }	
 for(i = rows - 1; i > 0; i--)
 {
 	for(j = 1; j <= rows - i; j++)
		{
 cout << " ";
 }
 for(k = 1; k <= i * 2 - 1; k++)
 {
 cout << "*";
 }
 cout << "\n";
 }
	
 	return 0;
}

Enter Diamond Star Pattern Row = 5
Diamond Star Pattern

Conclusion

As for the implementation part, we can use alphabets, or any other symbol for the pattern but the general will remain the same for always.
