C++ Number Pattern 42

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

example.cpp

Copied

#include <iostream>
using namespace std;

int main() {
  int i, j;
  for (i = 1; i <= 5; i++) {
    for (j = 1; j <= 5; j++) {
      if (i == 1 || i == 5 || j == 1 || j == 5)
        cout << "1 ";
      else
        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 starts with including the <iostream> library, which allows input and output operations.
The using namespace std; line is used to avoid writing std:: before the standard library functions.
The main() function is the entry point of the program. It returns an integer value.
Inside the main() function, two integer variables i and j, are declared to be used as loop counters.
The outer loop for(i=1; i<=5; i++) iterates from 1 to 5. It controls the rows of the pattern to be printed.
Inside the outer loop, there is an inner loop for(j=1; j<=5; j++) that iterates from 1 to 5. It controls the columns of the pattern to be printed.
Within the inner loop, there is an if condition that checks if the current row i is equal to 1 or 5 or if the current column j is equal to 1 or 5.
If the condition is true, it prints the character "1 " using the cout statement.
If the condition is false, it prints two spaces " " using the cout statement.
After printing each character, the control goes back to the inner loop to continue iterating until j reaches 5.
Once the inner loop is completed, a newline character \n is printed using the cout statement to move to the next row.
The outer loop continues iterating until i reaches 5.
After the outer loop completes, the main() function returns 0 to indicate successful program execution.
The program ends.

💯 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.
