C++ Alphabet Pattern 18

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;
  for (i = 65; i <= 69; i++) {
    for (j = 65; j <= i; j++)
      cout << char(j);
    for (k = i - 1; k >= 65; k--)
      cout << char(k);
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

Output

A
ABA
ABCBA
ABCDCBA
ABCDEDCBA

🧠 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 using namespace std; line tells the compiler that we'll be using the std namespace, which contains standard C++ library functions and objects.
The int main() function is the entry point of the program. It returns an integer value to indicate the status of the program's execution.
Inside the main() function, three integer variables i, j, and k are declared. These variables will be used for looping and storing character codes.
The first for loop initializes i with the value 65 (which corresponds to the ASCII code for the letter 'A') and continues the loop as long as i is less than or equal to 69 (which corresponds to the ASCII code for the letter 'E'). The loop increments i by 1 in each iteration.
Inside the first for loop, there is another nested for loop. The second for loop initializes j with the value 65 and continues the loop as long as j is less than or equal to i. In each iteration, it prints the character corresponding to the ASCII value of j using the cout statement.
After the second for loop, there is another nested for loop. The third for loop initializes k with the value of i-1 and continues the loop as long as k is greater than or equal to 65. In each iteration, it prints the character corresponding to the ASCII value of k using the cout statement.
After the third for loop, a newline character ("\n") is printed using cout to move the cursor to the next line.
The first for loop continues until i becomes 70, at which point the loop terminates.
Finally, the return 0; statement indicates that the program has executed successfully and returns the value 0 to the operating system.

💯 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.
