C++ Alphabet Pattern 29

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;
  // First Part
  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";
  }
  // Second Part
  for (i = 66; i <= k; 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
E D C B B B C D E
E D C C C C C D E
E D D D D D D D E
E E E E E E E E E

🧠 How the Program Works

Let's break down the logic behind the code:

The program includes the necessary header files: iostream for input/output operations and iomanip for stream manipulators.
The program starts with the main() function.
Inside main(), two integer variables i and j are declared, which will be used as loop counters.
Another integer variable k is declared and initialized with the value 69.
The program enters a for loop, starting with i initialized to the value of k and continuing as long as i is greater than or equal to 65. The loop decrements i by 1 in each iteration.
Inside the first loop, another for loop is used, starting with j initialized to the value of k and continuing as long as j is greater than or equal to 65. The loop decrements j by 1 in each iteration.
Inside the nested loop, an if statement checks if j is greater than i. If true, it prints the character corresponding to the ASCII value of j followed by a space. Otherwise, it prints the character corresponding to the ASCII value of i followed by a space.
After the nested loop, another for loop is used, starting with j initialized to 66 and continuing as long as j is less than or equal to k. The loop increments j by 1 in each iteration.
Inside this second nested loop, another if statement checks if j is greater than i. If true, it prints the character corresponding to the ASCII value of j followed by a space. Otherwise, it prints the character corresponding to the ASCII value of i followed by a space.
After the second nested loop, a newline character is printed using cout << "\n"; to move to the next line.
The first part of the pattern is completed, and the program continues with a similar pattern in the second part.
Another for loop is used, starting with i initialized to 66 and continuing as long as i is less than or equal to k. The loop increments i by 1 in each iteration.
Inside the second part loop, there is the same pattern as in the first part, but with a slight change. The nested loop now checks if j is greater than i instead of j being greater than i.
After the second part nested loop, a newline character is printed.
Once both parts of the pattern are completed, the program reaches the end of the main() function.
The program returns 0, indicating successful execution, using the statement return 0;.

💯 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.
