C++ Alphabet Pattern 15

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, k, m;
  for (i = 69; i >= 65; i--) {
    for (j = 65; j <= i; j++)
      cout << (char) j;
    for (k = i; k < 69; k++)
      cout << "**";
    for (m = i; m >= 65; m--)
      cout << (char) m;
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

Output

ABCDEEDCBA
ABCD**DCBA
ABC****CBA
AB******BA
A********A

🧠 How the Program Works

Let's break down the logic behind the code:

The program includes the necessary header file <iostream> to use input/output stream objects, such as cout.
The line using namespace std; tells the compiler to use the std namespace, which contains standard C++ library functions and objects.
The main() function is the entry point of the program.
Inside the main() function, several integer variables are declared: i, j, k, and m.
The first for loop initializes i with the value 69 and continues as long as i is greater than or equal to 65. It decrements i by 1 in each iteration.
Inside the first for loop, a nested loop is introduced. The second for loop initializes j with the value 65 and continues as long as j is less than or equal to the current value of i. It increments j by 1 in each iteration.
Inside the nested loop, the program prints the character corresponding to the ASCII value j using the cout object.
After the second loop, another nested loop is introduced. The third for loop initializes k with the current value of i and continues as long as k is less than 69. It increments k by 1 in each iteration.
Inside this loop, the program prints the string "**" using the cout object.
After the third loop, a fourth nested loop is introduced. The fourth for loop initializes m with the current value of i and continues as long as m is greater than or equal to 65. It decrements m by 1 in each iteration.
Inside this loop, the program prints the character corresponding to the ASCII value m using the cout object.
After all the nested loops, the program prints a newline character ("\n") using the cout object.
The first for loop continues to the next iteration, repeating the process until i is no longer greater than or equal to 65.
Finally, the program returns 0 to indicate successful execution of the main() function.

💯 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.
