C++ Alphabet Pattern 16

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

example.cpp

Copied

#include <iostream>
using namespace std;

int main() {
  int i, j;
  int k = 65;
  for (i = 65; i <= 69; i += 2) {
    for (j = 69; j >= 65; j--) {
      if (j > i)
        cout << " ";
      else
        cout << char(k++) << " ";
    }
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

Output

    A
  B C D
E F G H I

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts by including the necessary header file iostream which provides input/output stream functionality.
The line using namespace std; tells the program to use the std namespace, so we don't need to explicitly write std:: before standard library functions and objects.
The main() function is the entry point of the program. It has a return type of int, indicating that it should return an integer value when it finishes executing.
Inside the main() function, we declare two integer variables i and j without initializing them. These variables will be used as loop counters.
The next line declares an integer variable k and initializes it to 65. This variable k will be used to determine the ASCII value of characters to be printed.
The program enters a nested for loop. The outer loop iterates over the values of i from 65 to 69, incrementing i by 2 in each iteration.
Inside the outer loop, there is another nested for loop. The inner loop iterates over the values of j from 69 to 65, decrementing j by 1 in each iteration.
Inside the inner loop, there is an if-else statement that checks if j is greater than i. If it is, a space character is printed using cout << " ";. Otherwise, the else block is executed.
In the else block, the char(k++) expression is evaluated, which converts the ASCII value in k to its corresponding character and increments k by 1. The resulting character is then printed followed by a space using cout << char(k++) << " ";.
After the inner loop completes, a newline character is printed using cout << "\n";. This moves the output to the next line, creating a new row in the pattern.
The outer loop continues until the condition i <= 69 is no longer true.
Finally, the main() function ends with the statement return 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.
