C++ Number Pattern 27

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, k;
  for (i = 1; i <= 5; i++) {
    for (j = 1; j <= i; j++)
      cout << j;
    for (k = i - 1; k >= 1; k--)
      cout << k;
    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 starts with including the necessary header file iostream, which allows input and output operations in C++.
The line using namespace std; tells the program to use the std namespace, which contains standard C++ functions and objects.
The main() function is the entry point of the program. Execution begins from here.
Inside the main() function, three integer variables i, j, and k are declared without any initial values.
The outer for loop initializes i to 1 and repeats as long as i is less than or equal to 5. It increments i by 1 in each iteration.
Inside the outer for loop, there is an inner for loop that initializes j to 1 and repeats as long as j is less than or equal to i. It increments j by 1 in each iteration.
Inside the inner for loop, the statement cout << j; prints the value of j to the console.
After the inner for loop finishes, there is another inner for loop that initializes k to i-1 and repeats as long as k is greater than or equal to 1. It decrements k by 1 in each iteration.
Inside the second inner for loop, the statement cout << k; prints the value of k to the console.
After both inner for loops finish, the statement cout << "\n"; prints a newline character to the console, causing the next iteration of the outer for loop to start on a new line.
The outer for loop continues until i becomes 6, at which point it terminates.
Finally, the return 0; statement indicates that the program has executed successfully, and the main() function returns the value 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.
