C++ Alphabet Pattern 14

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 <= 74; i += 2) {
    for (j = 65; j <= i; j++)
      cout << (char) j;
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

Output

A
ABC
ABCDE
ABCDEFG
ABCDEFGHI

🧠 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 operations, and declares the std namespace for the standard library.
The main() function is the entry point of the program. It returns an integer value indicating the status of the program execution.
Two integer variables, i and j, are declared to be used in the loops.
The outer for loop initializes i with the value 65, tests if i is less than or equal to 74, and increments i by 2 in each iteration. This loop will run five times because (74 - 65) / 2 + 1 = 5.
Inside the outer loop, there is an inner for loop. It initializes j with the value 65, tests if j is less than or equal to i, and increments j by 1 in each iteration. The value of i determines the number of iterations for this inner loop. In the first iteration of the outer loop, the inner loop will run once (j = 65), in the second iteration, it will run twice (j = 65, 66), and so on.
Within the inner loop, the program prints the character corresponding to the ASCII value of j. The (char)j syntax casts the integer value j to a character.
After the inner loop completes for a given i value, the program prints a newline character "\n" to move to the next line.
The outer loop continues until i reaches 74, and the inner loop pattern keeps growing with each iteration.
Finally, the return 0; statement indicates that the program execution was successful, and the value 0 is returned 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.
