C++ Star Pattern 4

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 = 1; j < i; j++)
      cout << " ";
    for (k = 5; 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 starts with including the necessary header file iostream, which provides input/output stream functionality.
The line using namespace std; is used to avoid typing std:: before standard library functions and objects.
The main() function is the entry point of the program, where the execution begins.
Inside the main() function, three integer variables i, j, and k are declared to be used in the subsequent loops.
The outer loop for(i=1; i<=5; i++) runs from i = 1 to i = 5, and it controls the number of rows in the pattern.
Inside the outer loop, there are two nested loops.
The first nested loop for(j=1; j<i; j++) is responsible for printing spaces before the asterisks. It runs from j = 1 to j = i-1, and the number of spaces printed on each row increases as i increases.
The second nested loop for(k=5; k>=i; k--) is responsible for printing the asterisks. It runs from k = 5 to k = i, and the number of asterisks printed on each row decreases as i increases.
After printing the necessary spaces and asterisks, the line cout << "\n"; is used to move the output to the next line.
The outer loop repeats the above steps until i reaches the condition i <= 5.
Finally, the return 0; statement ends the main() function and returns a value of 0, indicating successful program execution.

💯 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.
