C Number Pattern 59

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

example.c

Copied

#include 

int main() {
 int i, j;
 int k = 6, l = 13, m = 16;

 // Outer loop for rows
 for (i = 1; i <= 5; i++) {
  // Inner loop for columns 
  for (j = 1; j <= 5; j++) {
   // Conditions to determine the number to be printed 
   if (i == 1) 
    printf("%-3d", j);
   else if (j == 5)
    printf("%-3d", k++);
   else if (i == 5)
    printf("%-3d", l--);
   else if (j == 1)
    printf("%-3d", m--);
   else
    printf("   ");
  }
  printf("\n");
 }

 return 0;
}

💻 Testing the Program

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

Output

1  2  3  4  5
16          6
15          7
14          8
13 12 11 10 9

🧠 How the Program Works

Let's break down the logic behind the code:

The program begins by declaring and initializing variables: i and j for the loop counters, and k, l, and m for the initial values of specific numbers to be printed.
The program uses two nested loops to iterate through the rows and columns of the pattern.
Inside the inner loop, several conditions are checked to determine which number to print in each position of the pattern.
If i (the current row) is equal to 1, it means it's the first row, so the numbers from 1 to 5 are printed in ascending order using the inner loop counter j.
If j (the current column) is equal to 5, it means it's the last column, so the variable k is printed and then incremented by one.
If i is equal to 5, it means it's the last row, so the variable l is printed and then decremented by one.
If j is equal to 1, it means it's the first column, so the variable m is printed and then decremented by one.
If none of the above conditions are true, it means it's an inner position in the pattern, and therefore, three spaces are printed to maintain the pattern's structure.
After printing each row, a newline character (\n) is printed to move to the next line.
The process continues for all five rows, resulting in the desired pattern.

The pattern that is printed resembles a square with numbers on its borders, with the top row displaying numbers from 1 to 5 in ascending order, the rightmost column displaying numbers from 6 to 10 in ascending order, the bottom row displaying numbers from 13 to 9 in descending order, and the leftmost column displaying numbers from 16 to 12 in descending order. The inner positions are filled with spaces to maintain the alignment of the pattern.

💯 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.
