C Alphabet Pattern 34

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

example.c

Copied

#include <stdio.h>

int main() {
  int i, j, k;
  // First Part
  for (i = 65; i <= 69; i++) {
    for (j = 69; j >= 65; j--) {
      if (i == j)
        printf("%c", j);
      else
        printf(" ");
    }
    for (k = 66; k <= 69; k++) {
      if (i == k)
        printf("%c", k);
      else
        printf(" ");
    }
    printf("\n");
  }
  // Second Part
  for (i = 68; i >= 65; i--) {
    for (j = 69; j >= 65; j--) {
      if (i == j)
        printf("%c", j);
      else
        printf(" ");
    }
    for (k = 66; k <= 69; k++) {
      if (i == k)
        printf("%c", k);
      else
        printf(" ");
    }
    printf("\n");
  }
  return 0;
}

💻 Testing the Program

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

Output

    A
   B B
  C   C
 D     D
E       E
 D     D
  C   C
   B B
    A

🧠 How the Program Works

Let's break down the logic behind the code:

Include the necessary header file stdio.h for input/output operations.
Define the main() function, which serves as the entry point of the program.
Declare three integer variables: i, j, and k.
First Part: Execute a nested loop to print the first part of the pattern. The outer loop iterates from 65 to 69 (ASCII values for characters A to E).
Within the outer loop, start the first inner loop from 69 (ASCII value for character E) and decrement j until it reaches 65 (ASCII value for character A).
In each iteration of the inner loop, check if i is equal to j. If they are equal, print the character represented by j. Otherwise, print a space.
Start the second inner loop from 66 (ASCII value for character B) and iterate up to 69 (ASCII value for character E).
In each iteration of the second inner loop, check if i is equal to k. If they are equal, print the character represented by k. Otherwise, print a space.
After completing both inner loops, print a newline character \n to move to the next line.
Repeat steps 5 to 9 for the remaining iterations of the outer loop.
Second Part: Execute another nested loop to print the second part of the pattern. The outer loop starts from 68 (ASCII value for character D) and decrements i until it reaches 65 (ASCII value for character A).
Within the outer loop, start the first inner loop from 69 (ASCII value for character E) and decrement j until it reaches 65 (ASCII value for character A).
In each iteration of the inner loop, check if i is equal to j. If they are equal, print the character represented by j. Otherwise, print a space.
Start the second inner loop from 66 (ASCII value for character B) and iterate up to 69 (ASCII value for character E).
In each iteration of the second inner loop, check if i is equal to k. If they are equal, print the character represented by k. Otherwise, print a space.
After completing both inner loops, print a newline character \n to move to the next line.
Repeat steps 12 to 16 for the remaining iterations of the outer loop.
Finally, return 0 to indicate successful execution of the program and terminate the main() function.

Each letter is printed in a triangular pattern with spaces to create the desired shape.

💯 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.
