C Star Pattern 7

The above star pattern is called Half hollow diamond pattern.

📄 Example

Here's a program that prints the above star pattern using C Programming:

example.c

Copied

#include <stdio.h>
int main()
{
 int i, j, k;
 for(i=1; i<=5; i++)
 {
  for(j=5; j>=1; j--) 
  {
   if(i == j)
    printf("*");
   else
    printf(" ");
  }
  for(k=2; k<=5; k++)
  {
   if(i == k)  
    printf("*");
   else
    printf(" ");
  }
  printf("\n");
 }
 return 0;
}

💻 Testing the Program

When you run the program, it will print the following pattern:

Output

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with the main() function declaration.
It includes the necessary header file stdio.h for standard input/output operations.
Three integer variables i, j, and k are declared to control the loops and track the current row and column.
The outer loop for(i=1; i<=5; i++) is used to iterate over the rows. It runs for i values from 1 to 5 (inclusive).
Inside the outer loop, the first inner loop for(j=5; j>=1; j--) is used to print spaces or asterisks in a decreasing manner from right to left. It runs for j values from 5 to 1 (inclusive).
- If the current row i is equal to the current column j, it means we are in the position to print an asterisk in the pattern. So, if(i == j) condition is checked, and if true, an asterisk is printed.
- If the current row i is not equal to the current column j, it means we need to print a space in that position. So, the else block is executed, and a space is printed.
After the first inner loop, a second inner loop for(k=2; k<=5; k++) is used to print spaces or asterisks in an increasing manner from left to right. It runs for k values from 2 to 5 (inclusive).
- If the current row i is equal to the current column k, it means we are in the position to print an asterisk in the pattern. So, if(i == k) condition is checked, and if true, an asterisk is printed.
- If the current row i is not equal to the current column k, it means we need to print a space in that position. So, the else block is executed, and a space is printed.
After both inner loops, a newline character is printed using printf("\n") to move to the next line before starting the next row.
The outer loop repeats steps 5 to 7 for each row of the pattern.
Finally, the main() function returns 0 to indicate successful program execution.

The program uses the concept of nested loops to control the row and column positions and conditional statements to determine whether to print an asterisk or a space in each position. The combination of these loops and conditions creates the desired 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.
