C++ Alphabet Pattern 20

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

💻 Testing the Program

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

Output

    A
   BA
  CBA
 DCBA
EDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts by including the necessary header file iostream which allows input/output operations.
The statement using namespace std; tells the program to use the standard namespace, which means you don't have to prefix standard library functions and objects with std::.
The main() function is the entry point of the program and the execution starts from here.
Two integer variables i and j are declared without any initial values.
The first for loop initializes i with the ASCII value of 'A' (which is 65) and iterates until i reaches the ASCII value of 'E' (which is 69).
Inside the first loop, another for loop is used to initialize j with the ASCII value of 'E' and decrement it until it reaches the ASCII value of 'A'.
Inside the inner loop, an if statement checks if j is greater than i.
If j is greater than i, it means we are at a position where we need to print a space. So, the program prints a space using cout << " ";.
If the condition in the if statement is not true, the else block is executed.
In the else block, the program prints the character corresponding to the ASCII value of j using cout << char(j);. Since j is decremented in each iteration of the inner loop, it prints the characters in reverse order from 'E' to 'A'.
After the inner loop finishes, the program moves to the next line using cout < < "\n"; to print a new line.
This process continues for each value of i in the outer loop, resulting in a pattern of characters being printed.
Once both the loops finish executing, the program reaches the end of the main() function.
The statement return 0; indicates that the program has completed successfully and returns 0 as the exit status 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.
