C Alphabet Pattern 32

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, m, n;
  for (i = 65; i <= 69; i++) {
    for (j = 69; j >= i; j--)
      printf(" ");
    for (k = 65; k <= i; k++)
      printf("%c", k);
    n = k - 1;
    for (m = 65; m < i; m++)
      printf("%c", --n);
    printf("\n");
  }
  return 0;
}

💻 Testing the Program

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

Output

    A
   ABA
  ABCBA
 ABCDCBA
ABCDEDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts by including the standard input/output library stdio.h, which provides functions like printf for displaying output on the screen.
The main() function is the entry point of the program. It returns an integer value, in this case, 0, to indicate successful execution.
Inside the main() function, several integer variables are declared: i, j, k, m, and n. These variables will be used in the subsequent loops for controlling the iteration and storing temporary values.
The outer for loop is used to iterate over the values of i from 65 to 69 (inclusive). These values correspond to the ASCII codes of characters 'A' to 'E'.
Within the outer loop, the first inner for loop is used to print spaces before each line of the pattern. It starts with j initialized to 69 (the ASCII code for 'E') and decrements j for each iteration until it becomes equal to i. This creates a decreasing number of spaces before each line as i increases.
After the spaces, the second inner for loop is used to print the characters in increasing order. It starts with k initialized to 65 (the ASCII code for 'A') and increments k for each iteration until it becomes equal to i. This prints the characters 'A' to the current value of i in ascending order.
The value of k is then assigned to n, and n is decremented by 1. This step prepares for printing the characters in decreasing order in the next loop.
The third inner for loop is used to print the characters in decreasing order. It starts with m initialized to 65 (the ASCII code for 'A') and continues until it becomes equal to i - 1. In each iteration, it prints the character corresponding to the current value of n (which is decremented in each iteration).
After the inner loops, a newline character "\n" is printed using printf() to move to the next line, forming the pyramid pattern.
The outer loop continues until i becomes 70. Since the condition i<=69 is specified, the loop executes for values of i from 65 to 69, inclusive.
Finally, the program exits the main() function and returns 0, indicating successful 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.
