C++ Alphabet Pattern 9

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

💻 Testing the Program

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

Output

A
BB
CCC
DDDD
EEEEE

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with including the necessary header file iostream, 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, where the execution begins.
Inside the main() function, two integer variables i and j are declared without any initial values.
The first for loop initializes i with the ASCII value of the character 'A' (which is 65) and continues until i is less than or equal to the ASCII value of the character 'E' (which is 69). This loop controls the number of rows in the output pattern.
Inside the first for loop, there is another nested for loop that initializes j with the ASCII value of the character 'A' and continues until j is less than or equal to the value of i. This nested loop controls the number of characters printed in each row.
Within the nested loop, the statement cout << (char)i; prints the character represented by the current value of i. Since i is an ASCII value, it is typecast to char to print the corresponding character.
After the nested loop, the statement cout << "\n"; is executed to print a newline character. This moves the output to the next line, creating a new row in the pattern.
Once the inner for loop completes for a given value of i, the control returns to the outer for loop, and the process repeats until i exceeds the value 69.
Finally, the return 0; statement indicates that the program execution is successful and returns the value 0 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.
