C Alphabet Pattern 15

Here`s a program that prints the above alphabet pattern using C Programming:

example.c

Copied

#include <stdio.h>

int main() {
 int i, j;
 char ch;

 for (i = 5; i >= 1; i--) {
  ch = 'A';

  for (j = 1; j <= i; j++) {
   printf("%c", ch++);
  }

  for (j = 1; j <= 2 * (5 - i); j++) {
   printf("*");
  }

  ch--; 

  for (j = 1; j <= i; j++) {
   printf("%c", ch--);
  }

  printf("\n");
 }

 return 0;
}

💻 Testing the Program

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

Output

ABCDEEDCBA
ABCD**DCBA
ABC****CBA
AB******BA
A********A

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts by including the necessary header file, stdio.h, to enable input/output operations.
The program declares variables: i and j as loop counters, and ch to represent the character to be printed.
The program uses a nested for loop to print the pattern.
The outer loop, i, iterates from 5 to 1 in reverse order, representing the number of rows in the pattern.
Inside the outer loop, the program initializes ch to the character 'A'.
The first inner loop, j, iterates from 1 to i, printing the characters from 'A' to the current value of ch using printf("%c", ch++).
After printing the initial characters, the second inner loop, j, iterates from 1 to 2 * (5 - i), printing asterisks (*) using printf("*").
- The number of asterisks is determined by the difference between 5 and the current value of i.
- This loop creates the hollow portion of the pattern.
After printing the asterisks, the program decrements ch to the previous character.
The third inner loop, j, iterates from 1 to i, printing the characters from the current value of ch to 'A' using printf("%c", ch--).
- This loop prints the reverse of the characters printed in the first inner loop.
After each row is printed, a newline character (\n) is printed using printf("\n") to move to the next line.
This process is repeated for each value of i in the outer loop, resulting in the pattern being printed.
The program terminates by returning 0.

In this pattern, each line consists of a sequence of characters that starts with 'A', incrementally adds one character until the middle of the line, includes a hollow portion represented by asterisks (*), and then reverses the characters back to 'A'. The number of characters and asterisks in each line is determined by the line number and the pattern's symmetry.

💯 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.
