C++ Number Pattern 50

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 > 1; j--)
      cout << j;
    for (k = 1; k <= 6 - i; 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 by including the necessary header file <iostream>, which provides input and output stream functionalities.
The statement using namespace std; allows us to use elements from the std namespace (Standard C++ Library) without explicitly specifying it. In this case, it will allow us to use cout without writing std::cout every time.
The main() function is the entry point of the program, where the execution starts.
Three integer variables i, j, and k are declared to be used later in the program.
The first for loop initializes i to 1 and continues as long as i is less than or equal to 5. The loop will increment i by 1 after each iteration.
Inside the first for loop, there are two more loops:
1. The first nested for loop initializes j to the value of i and continues as long as j is greater than 1. It will decrement j by 1 after each iteration.
2. The second nested for loop initializes k to 1 and continues as long as k is less than or equal to 6 - i. It will increment k by 1 after each iteration.
The first nested loop prints the value of j on each iteration, and the second nested loop prints the value of k on each iteration.
After both nested loops, a newline character "\n" is printed to move to the next line before the next iteration of the outer loop.
The program will repeat steps 5-8 until i becomes greater than 5, at which point the outer for loop will terminate.
Finally, the main() function returns 0, indicating successful program execution, and 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.
