C++ Star Pattern 2

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;
  for (i = 5; i >= 1; i--) {
    for (j = 1; j <= i; j++)
      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 iostream library, which allows input and output operations, such as printing to the console.
The using namespace std; line tells the compiler to use the std namespace, which contains standard C++ library functions and objects.
The main() function is the entry point of the program. It is where the execution of the program begins.
Inside the main() function, two integer variables i and j are declared without any initial values.
The outer for loop is used to control the number of rows in the pattern. It starts with i initialized to 5, and the loop continues as long as i is greater than or equal to 1. In each iteration, i is decremented by 1.
Inside the outer for loop, there is an inner for loop. This loop controls the number of asterisks (*) to be printed in each row. It starts with j initialized to 1 and continues as long as j is less than or equal to i. In each iteration, j is incremented by 1.
Inside the inner for loop, the statement cout << "*"; is used to print an asterisk (*) to the console.
After the inner for loop completes, the statement cout << "\n"; is used to print a newline character, which moves the cursor to the next line for the next row.
The outer for loop continues its iterations until i becomes less than 1, at which point it terminates.
Finally, the return 0; statement is used to exit the main() function and indicate that the program has run successfully. The value 0 is returned to the operating system.

💯 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.
