C++ Number Pattern 37

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 = i; j > 1; j--)
      cout << j;
    for (j = 1; j <= i; j++)
      cout << j;
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

🧠 How the Program Works

Let's break down the logic behind the code:

The program begins by including the necessary header file <iostream> which provides input/output stream functionality. The using namespace std; line is used to avoid writing std:: before standard library functions.
The main() function is the entry point of the program. It has a return type of int, indicating that it should return an integer value when it completes.
Two integer variables i and j are declared.
The outer for loop initializes i to 1 and repeats as long as i is less than or equal to 5. The loop increments i by 1 in each iteration.
Inside the outer loop, there is an inner loop. The inner for loop initializes j to the current value of i and continues as long as j is greater than 1. The loop decrements j by 1 in each iteration.
Within the inner loop, the statement cout << j; is executed, which prints the current value of j to the console.
After the inner loop finishes, there is another inner loop. This loop initializes j to 1 and continues as long as j is less than or equal to the current value of i. The loop increments j by 1 in each iteration.
Inside this second inner loop, the statement cout << j; is executed, printing the current value of j to the console.
After the second inner loop finishes, the statement cout << "\n"; is executed, which prints a newline character to the console. This causes the output to appear on separate lines.
The outer loop then repeats, and the entire process continues until i becomes greater than 5.
Finally, the return 0; statement is executed, indicating that the program has completed successfully and returns 0 to the operating system.

💯 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.
