C++ Star Pattern 7

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 >= 1; j--) {
      if (i == j)
        cout << "*";
      else
        cout << " ";
    }
    for (k = 2; k <= 5; k++) {
      if (i == k)
        cout << "*";
      else
        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 includes the necessary header file, <iostream>, which allows us to use input and output stream objects such as cin and cout.
The line using namespace std; tells the compiler that we want to use the standard namespace. This simplifies the code by allowing us to write cout instead of std::cout, for example.
The main() function is the entry point of the program and where the execution begins.
Inside the main() function, three integer variables i, j, and k are declared. These variables will be used as loop counters and control the flow of the program.
The outer for loop initializes i to 1 and continues as long as i is less than or equal to 5. It increments i by 1 after each iteration.
Inside the outer for loop, there are two nested for loops.
The first nested for loop initializes j to 5 and continues as long as j is greater than or equal to 1. It decrements j by 1 after each iteration.
Inside this loop, there is an if statement that checks if i is equal to j. If the condition is true, it means the values of i and j are the same, so an asterisk * is printed using cout << "*". Otherwise, a space character is printed.
After the first nested for loop, there is a second nested for loop.
The second nested for loop initializes k to 2 and continues as long as k is less than or equal to 5. It increments k by 1 after each iteration.
Inside this loop, there is another if statement that checks if i is equal to k. If the condition is true, an asterisk * is printed using cout << "*". Otherwise, a space character is printed.
After the second nested for loop, a newline character (\n) is printed using cout << "\n". This moves the cursor to the next line, creating a new line for the next iteration of the outer for loop.
The program continues with the next iteration of the outer for loop until i becomes greater than 5.
Finally, the return 0; statement indicates that the program has finished executing and returns the value 0 to the operating system, indicating successful termination.

💯 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.
