C++ Star Pattern 11

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

example.cpp

Copied

#include <iostream>
using namespace std;

int main() {
  int i, j, k;
  for (i = 1; i <= 5; i++) {
    for (j = i; j <= 5; j++)
      cout << "*";
    for (k = 1; k < (i * 2) - 1; k++)
      cout << " ";
    for (j = i; j <= 5; j++)
      cout << "*";
    for (k = 1; k < i * 2; k++)
      cout << " ";
    cout << "\n";
  }
  for (i = 4; i >= 1; i--) {
    for (j = 5; j >= i; j--)
      cout << "*";
    for (k = 1; k < (i * 2) - 1; k++)
      cout << " ";
    for (j = 5; j >= i; j--)
      cout << "*";
    for (k = 1; k < i * 2; k++)
      cout << " ";
    cout << "\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 includes the necessary header file iostream for input/output stream operations.
The program uses the using namespace std; statement to indicate that the program will use the standard C++ namespace.
The main() function is the entry point of the program and is where the execution begins.
Four integer variables i, j, and k are declared to be used in loops.
The first for loop is used to create the top half of the pattern, which consists of stars (*) and spaces. It runs for i from 1 to 5.
The first nested for loop (with j) is used to print i stars in each row. It starts with the current value of i and goes up to 5, printing the stars.
The second nested for loop (with k) is used to print spaces. It runs from 1 to (i*2)-1, which means the number of spaces in each row increases by 2 in each iteration.
The third nested for loop (with j) is used to print the stars again. This loop is similar to the first nested loop and runs from i to 5.
The fourth nested for loop (with k) is used to print additional spaces after the stars. It runs from 1 to i*2.
After each row is printed, a new line (\n) is added to move to the next row.
After the top half of the pattern is printed, the program uses another for loop to create the bottom half of the pattern. This loop runs for i from 4 to 1.
The nested for loops in this section perform similar tasks as in the top half, but in reverse order. The number of stars decreases and the number of spaces increases in each row.
The program continues to print the bottom half of the pattern.
After the bottom half is printed, the main() function returns 0 to indicate successful program execution.

💯 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.
