C++ Star Pattern 3

Here`s a program that prints the above star pattern using C++ Programming:

example.cpp

Copied

#include <iostream>
using namespace std;

int main() {
  int i, j, k;
  for (i = 1; i <= 5; i++) {
    for (j = 5; j > i; j--)
      cout << " ";
    for (k = 1; k <= i; k++)
      cout << "*";
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

When you run the above program, it will print the following output:

Output

    *
   **
  ***
 ****
*****

🧠 How the Program Works

Let's break down the logic behind the code:

The program begins with the inclusion of the <iostream> library, which allows input and output operations, and the using namespace std; statement, which eliminates the need to explicitly specify the namespace for standard library elements.
The main() function is the entry point of the program.
Inside the main() function, three integer variables i, j, and k are declared. These variables will be used as counters in the loops.
The first for loop is the outer loop with the variable i. It initializes i to 1, executes the loop as long as i is less than or equal to 5, and increments i by 1 in each iteration.
Inside the outer loop, there are two nested for loops.
The second for loop is the first inner loop with the variable j. It initializes j to 5, executes the loop as long as j is greater than i, and decrements j by 1 in each iteration. This loop is responsible for printing spaces before the stars.
Inside the second loop, there is a cout statement that prints a space character (" ") on the console.
The third for loop is the second inner loop with the variable k. It initializes k to 1, executes the loop as long as k is less than or equal to i, and increments k by 1 in each iteration. This loop is responsible for printing the stars.
Inside the third loop, there is another cout statement that prints an asterisk character ("*") on the console.
After the two inner loops, there is a cout statement that prints a newline character ("\n") on the console. This moves the cursor to the next line after each row of stars is printed.
The program continues executing the outer loop until i becomes 6 (i.e., when the condition i <= 5 is no longer true).
Once the outer loop is finished, the program reaches the return 0; statement, which indicates successful program execution, and the main() function ends.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.
