C++ Alphabet Pattern 25

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;
  int k = 65;
  for (i = 65; i <= 69; i++) {
    for (j = 69; j >= i; j--)
      cout << setw(2) << 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 two header files: iostream and iomanip. These header files provide input/output stream functionality and manipulators for formatting output, respectively.
The using namespace std; line allows you to use names from the std namespace directly, without needing to specify the namespace each time.
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 initialized with the value 65. This variable will be used to generate characters starting from 'A' (ASCII value 65).
The outer for loop iterates from i = 65 to 69. This loop controls the rows of the output pattern.
Inside the outer loop, there is an inner for loop that iterates from j = 69 to i. This loop controls the columns of the output pattern.
Within the inner loop, the program prints the character corresponding to the current value of k, using the setw(2) manipulator to ensure each character is printed with a width of 2. The char(k++) expression converts the integer value k to the corresponding character based on the ASCII table and then increments k.
After the inner loop finishes, the program prints a newline character to move to the next line in the output.
The outer loop continues to the next iteration, and the inner loop repeats the character printing process with a different number of iterations.
Once the outer loop finishes executing, the main() function ends with a return 0; statement, indicating successful program execution.

💯 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.
