C Number Pattern 62

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

example.c

Copied

#include <stdio.h>

#define SIZE 10

int main() {
 int matrix[SIZE][SIZE];
 int i, j, num = 1;
 int row_start = 0, row_end = SIZE - 1;
 int col_start = 0, col_end = SIZE - 1;

 while (num <= SIZE * SIZE) {
  for (i = col_start; i <= col_end; i++)
   matrix[row_start][i] = num++;
  row_start++;

  for (i = row_start; i <= row_end; i++)
   matrix[i][col_end] = num++;
  col_end--;

  for (i = col_end; i >= col_start; i--)
   matrix[row_end][i] = num++;
  row_end--;

  for (i = row_end; i >= row_start; i--)
   matrix[i][col_start] = num++;
  col_start++;
 }

 for (i = 0; i < SIZE; i++) {
  for (j = 0; j < SIZE; j++)
   printf("%4d", matrix[i][j]);
  printf("\n");
 }

 return 0;
}

💻 Testing the Program

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

Output

🧠 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 defines a constant SIZE with a value of 10, representing the size of the matrix.
The program declares a 2D array called matrix with dimensions SIZE x SIZE to store the numbers for the pattern.
The program initializes several variables: i, j for loop counters, num to keep track of the current number to be placed in the matrix, and row_start, row_end, col_start, and col_end to track the boundaries of the current spiral.
The program uses a while loop to fill the matrix in a spiral pattern.
Inside the loop, there are four separate loops to fill the top row, right column, bottom row, and left column of the current spiral, respectively.
The first loop fills the top row from left to right and increments num after each placement.
The second loop fills the right column from top to bottom and increments num after each placement.
The third loop fills the bottom row from right to left and increments num after each placement.
The fourth loop fills the left column from bottom to top and increments num after each placement.
After each loop, the corresponding boundary variables (row_start, row_end, col_start, col_end) are adjusted to move to the next inner spiral.
The loop continues until all the numbers from 1 to SIZE x SIZE are placed in the matrix.
Finally, the program uses nested for loops to print the matrix, formatting each number with a width of 4 characters.
The program terminates by returning 0.

💯 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.
