C++ Alphabet Pattern 23

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;
  for (i = 69; i >= 65; i--) {
    for (j = 65; j < i; j++)
      cout << "  ";
    for (j = 69; j >= i; j--)
      cout << setw(2) << char(j);
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

Output

        E
      E D
    E D C
  E D C B
E D C B A

🧠 How the Program Works

Let's break down the logic behind the code:

The program begins with including two standard C++ libraries: iostream and iomanip. These libraries provide functionality for input/output operations and formatting output respectively.
The using namespace std; statement allows you to use names from the std namespace directly without explicitly specifying it.
The main() function is the entry point of the program.
Two integer variables, i and j, are declared.
The outer for loop initializes i with the value 69 and continues as long as i is greater than or equal to 65. The loop decrements i by 1 in each iteration.
Inside the outer loop, there is another for loop that initializes j with the value 65 and continues as long as j is less than i. The loop increments j by 1 in each iteration.
Inside the second loop, there is a cout statement that outputs two spaces to create indentation. The number of spaces printed depends on the value of i in the outer loop.
After the second loop, there is another for loop that initializes j with the value 69 and continues as long as j is greater than or equal to i. The loop decrements j by 1 in each iteration.
Inside the third loop, there is a cout statement that outputs the character represented by the ASCII value of j. The setw(2) function from the iomanip library is used to set the width of the output to 2 characters. This ensures that each character is printed with a fixed width, even if the ASCII value is less than 10.
After printing the characters, a new line is printed using cout << "\n";.
The outer loop continues until i becomes less than 65.
Finally, the main() function returns 0, indicating successful execution of the program.

💯 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.
