C Number Pattern 31

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

example.c

Copied

#include <stdio.h>

int main() {
 int rows = 5;

 // Print upper half of the pattern
 for (int i = 1; i <= rows; i++) {
  // Print numbers in ascending order  
  for (int j = 1; j <= i; j++) {
   printf("%d", i);

   // Print asterisk (*) if it's not the last number in the row
   if (j != i) {
    printf("*");
   }
  }

  printf("\n");
 }

 // Print lower half of the pattern
 for (int i = rows - 1; i >= 1; i--) {
  // Print numbers in ascending order
  for (int j = 1; j <= i; j++) {
   printf("%d", i);

   // Print asterisk (*) if it's not the last number in the row
   if (j != i) {
    printf("*");
   }
  }

  printf("\n");
 }

 return 0;
}

💻 Testing the Program

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

Output

1
2*2
3*3*3
4*4*4*4
5*5*5*5*5
4*4*4*4
3*3*3
2*2
1

🧠 How the Program Works

Let's break down the logic behind the code:

We define the number of rows to be 5.
The first loop is used to print the upper half of the pattern. It iterates from i = 1 to rows.
Inside this loop, the second loop is used to print the numbers in ascending order. It starts from j = 1 and goes up to i, printing the number i for each iteration.
After printing each number, an asterisk (*) is printed if it's not the last number in the row.
Once the upper half is printed, the program enters the second loop to print the lower half of the pattern. This loop iterates from i = rows - 1 to 1, printing the numbers in descending order.
The rest of the logic remains the same as the upper half printing loop, printing the numbers and asterisks accordingly.

The pattern consists of numbers in each row, separated by asterisks (*). The upper half of the pattern starts with the number 1 and increments by one for each row. The lower half is a mirror image of the upper half, with the numbers decreasing.

💯 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.
