C Number Pattern 51

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

example.c

Copied

#include <stdio.h>

int main() {
 int row, col, num = 1;

 for (row = 1; row <= 5; row++) {
  if (row % 2 == 0) {
   for (col = num + row - 1; col >= num; col--) {
    printf("%2d ", col);
   }
  } else {
   for (col = num; col < num + row; col++) {
    printf("%2d ", col);
   }
  }
  printf("\n");
  num += row;
 }

 return 0;
}

💻 Testing the Program

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

Output

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

🧠 How the Program Works

Let's break down the logic behind the code:

The outer loop (row) runs from 1 to 5, representing the row number in the pattern.
Inside the outer loop, there is an if-else condition to determine whether the row is odd or even.
If the row is odd, the program enters the else block and executes the first inner loop (col incrementing from num to num + row - 1).
- The variable num keeps track of the current starting number of each row.
- The loop prints the numbers from num to num + row - 1 with a space after each number.
If the row is even, the program enters the if block and executes the second inner loop (col decrementing from num + row - 1 to num).
- This loop prints the numbers from num + row - 1 to num with a space after each number.
After printing the numbers in the current row, the program moves to the next line using printf("\n") to start a new row.
The value of num is incremented by row at the end of each row to update it for the next row.
The outer loop continues until all the rows specified in the loop condition (row <= 5) are generated.
Finally, the program exits by returning 0.

This program generates a number pattern where each row contains a series of numbers. The odd rows are printed in ascending order starting from 1 and increasing by 1 in each position, while the even rows are printed in descending order starting from the largest number in the previous row and decreasing by 1 in each position. For example, the first row contains only 1, the second row contains 3 2, the third row contains 4 5 6, and so on.

💯 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.
