C++ Alphabet Pattern 32

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, n;
  for (i = 65; i <= 69; i++) {
    for (j = 69; j >= i; j--)
      cout << " ";
    for (k = 65; k <= i; k++)
      cout << char(k);
    n = k - 1;
    for (m = 65; m < i; m++)
      cout << char(--n);
    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 with the inclusion of the <iostream> library, which allows input and output operations in C++. The using namespace std; statement is used to avoid typing std:: before standard library functions.
The main() function is the entry point of the program and where the execution begins.
The variable declarations i, j, k, m, and n are used for iteration and storing intermediate values.
The outer for loop initializes i with the value 65 (ASCII value for 'A') and continues as long as i is less than or equal to 69 (ASCII value for 'E'). It increments i by 1 in each iteration.
Inside the outer loop, there is a nested for loop with an initialization of j as 69 (ASCII value for 'E'). The inner loop continues as long as j is greater than or equal to i. It decrements j by 1 in each iteration.
Within the inner loop, a space character is printed using cout to create a triangular pattern of spaces before the characters.
After the inner loop, there is another nested for loop with an initialization of k as 65 (ASCII value for 'A'). It continues as long as k is less than or equal to i. It increments k by 1 in each iteration.
Inside this loop, the char(k) function is used to convert the ASCII value k to its corresponding character and then printed using cout. This prints the characters in ascending order from 'A' to the current value of i.
The value of k is stored in n after the loop execution.
Another for loop with an initialization of m as 65 (ASCII value for 'A') starts. It continues as long as m is less than i. It increments m by 1 in each iteration.
Inside this loop, the char(--n) function is used to decrement the value of n by 1 and convert it to its corresponding character, which is then printed using cout. This prints the characters in descending order from the previous value of n to 'A'.
Finally, a newline character ("\n") is printed using cout to move to the next line after each iteration of the outer loop.
After the outer loop completes, the main() function returns 0, indicating 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.
