C++ Alphabet Pattern 28

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

example.cpp

Copied

#include <iostream>
#include <iomanip>
using namespace std;

int main() {
  int i, j;
  int k = 69;
  for (i = k; i >= 65; i--) {
    for (j = k; j >= 65; j--) {
      if (j > i)
        cout << char(j) << " ";
      else
        cout << char(i) << " ";
    }
    for (j = 66; j <= k; j++) {
      if (j > i)
        cout << char(j) << " ";
      else
        cout << char(i) << " ";
    }
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

Output

E E E E E E E E E
E D D D D D D D E
E D C C C C C D E
E D C B B B C D E
E D C B A B C D E

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts by including two C++ standard libraries: <iostream> and <iomanip>. These libraries provide input/output and formatting functionalities.
The using namespace std; line allows us to use names from the std namespace without explicitly specifying it, such as cout and endl.
The main() function is the entry point of the program.
Two integer variables i and j are declared without any initial values.
Another integer variable k is declared and assigned the value 69.
The program enters a nested for loop. The outer loop initializes i with the value of k and continues as long as i is greater than or equal to 65. The loop decrements i by 1 in each iteration.
Inside the outer loop, there is another nested for loop. The inner loop initializes j with the value of k and continues as long as j is greater than or equal to 65. The loop decrements j by 1 in each iteration.
Within the inner loop, there is an if statement that checks if the current value of j is greater than the current value of i.
If the condition j > i is true, it means we are in the upper triangle of the pattern, so it prints the character represented by the ASCII value of j followed by a space. The char(j) statement converts the ASCII value to the corresponding character.
If the condition j > i is false, it means we are in the lower triangle of the pattern, so it prints the character represented by the ASCII value of i followed by a space.
After the inner loop completes, there is another nested for loop. This loop initializes j with the value 66 (ASCII value of 'B') and continues as long as j is less than or equal to k. The loop increments j by 1 in each iteration.
Inside this loop, there is a similar if statement that checks if the current value of j is greater than the current value of i.
If the condition j > i is true, it means we are in the upper triangle of the pattern, so it prints the character represented by the ASCII value of j followed by a space.
If the condition j > i is false, it means we are in the lower triangle of the pattern, so it prints the character represented by the ASCII value of i followed by a space.
After the second nested loop completes, a newline character "\n" is printed to move to the next line.
The outer loop continues until i is no longer greater than or equal to 65, and the pattern is printed row by row.
Finally, the main() function returns 0 to indicate 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.
