C++ Alphabet Pattern 34

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

example.cpp
Copied
Copy To Clipboard
#include <iostream>
using namespace std;

int main() {
  int i, j, k;
  for (i = 65; i <= 69; i++) {
    for (j = 69; j >= 65; j--) {
      if (i == j)
        cout << char(j);
      else
        cout << " ";
    }
    for (k = 66; k <= 69; k++) {
      if (i == k)
        cout << char(k);
      else
        cout << " ";
    }
    cout << "\n";
  }
  for (i = 68; i >= 65; i--) {
    for (j = 69; j >= 65; j--) {
      if (i == j)
        cout << char(j);
      else
        cout << " ";
    }
    for (k = 66; k <= 69; k++) {
      if (i == k)
        cout << char(k);
      else
        cout << " ";
    }
    cout << "\n";
  }
  return 0;
}

๐Ÿ’ป Testing the Program

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

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

๐Ÿง  How the Program Works

Let's break down the logic behind the code:

  1. The program starts by including the necessary header file iostream, which provides input/output stream functionality.
  2. The line using namespace std; allows the use of standard library functions and objects without explicitly specifying the std:: namespace.
  3. The main() function is the entry point of the program.
  4. Inside the main() function, there are several variables declared: i, j, and k, all of type int. These variables are used as loop counters.
  5. The first for loop initializes i to 65 and iterates as long as i is less than or equal to 69. In each iteration, the loop increments i by 1.
  6. Inside the first for loop, there is a nested for loop that initializes j to 69 and iterates as long as j is greater than or equal to 65. In each iteration, the loop decrements j by 1.
  7. Inside the nested for loop, there is an if statement that checks if i is equal to j. If the condition is true, it means that i and j have the same value, and the corresponding character is printed using cout << char(j). Otherwise, a space character is printed using cout << " ".
  8. After the nested for loop, there is another nested for loop that initializes k to 66 and iterates as long as k is less than or equal to 69. In each iteration, the loop increments k by 1.
  9. Inside this nested for loop, there is another if statement that checks if i is equal to k. If the condition is true, it means that i and k have the same value, and the corresponding character is printed using cout << char(k). Otherwise, a space character is printed using cout << " ".
  10. After the nested for loops, a newline character is printed using cout << "\n". This moves the output to the next line.
  11. The first for loop continues to iterate until i is no longer less than or equal to 69. At this point, the program continues to the next block of code.
  12. The second for loop is similar to the first one, but it initializes i to 68 and decrements i by 1 in each iteration.
  13. Inside this second loop, the same pattern of nested for loops and if statements is followed as in the first loop, resulting in a reversed pattern being printed.
  14. Finally, after the second for loop, a newline character is printed using cout << "\n".
  15. The program reaches the end of the main() function, and the value 0 is returned, indicating successful execution of the program.
  16. The program ends.

๐Ÿ’ฏ 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.
