C++ Number Pattern 39

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 = i; j <= 5; j++)
      cout << j;
    for (k = i; k > 1; k--)
      cout << k - 1;
    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 provides input/output stream functionalities in C++.
The line using namespace std; is used to bring the std namespace into the current scope. This allows you to use C++ standard library functions and objects without specifying the namespace explicitly.
The main() function is the entry point of the program and where the execution begins.
Inside the main() function, three integer variables i, j, and k are declared.
The outer for loop initializes i to 1 and continues as long as i is less than or equal to 5. It increments i by 1 in each iteration.
Inside the outer loop, there are two nested for loops and an output statement.
The first nested for loop initializes j to the current value of i and continues as long as j is less than or equal to 5. It increments j by 1 in each iteration.
The statement cout << j; prints the value of j to the standard output (usually the console).
After the first nested loop, there is a second nested for loop.
The second nested for loop initializes k. to the current value of i and continues as long as k is greater than 1. It decrements k by 1 in each iteration.
The statement cout << k-1; prints the value of k-1 to the standard output.
After the second nested loop, the statement cout << "\n"; prints a newline character, which moves the output to the next line.
The outer for loop continues to the next iteration, and the process is repeated until i exceeds the value of 5.
Finally, the return 0; statement indicates the end of the main() function and the successful termination of the program.

💯 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.
