C++ Alphabet Pattern 13

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

💻 Testing the Program

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

Output

A
B C
D E F
G H I J
K L M N O

🧠 How the Program Works

Let's break down the logic behind the code:

The program includes the necessary header file <iostream> which provides input/output functionality, and using namespace std; to avoid typing std:: before standard library functions and objects.
The main() function is the entry point of the program.
Two integer variables i and j are declared.
Another integer variable k is declared and assigned the value 65. This value corresponds to the ASCII code of the letter 'A'.
The program enters a nested for loop. The outer loop iterates from i=65 to i<=69, which means it will execute five times.
Inside the outer loop, there is another for loop that iterates from j=65 to j<=i. The value of i changes with each iteration of the outer loop, starting from 65. This inner loop controls the number of characters to be printed on each line.
Within the inner loop, the program prints the character represented by the ASCII value stored in k, and then increments k by one. The (char) type cast is used to convert the integer value of k to its corresponding character. Since k starts at 65 (ASCII code for 'A'), each time it is incremented, it represents the next character in the ASCII sequence ('B', 'C', and so on).
After printing each character, a space is also printed to separate them.
Once the inner loop finishes, a newline character "\n" is printed to move to the next line.
The outer loop continues its execution until i reaches 69.
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.
