C++ Number Pattern 36

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

example.cpp

Copied

#include <iostream>
#include <iomanip>
using namespace std;

int main() {
  int i, j;
  for (i = 5; i >= 1; i--) {
    for (j = 1; j < i; j++)
      cout << "  ";
    for (j = 5; j >= i; j--)
      cout << setw(2) << 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 includes two header files: <iostream> and <iomanip>. These headers are required for input-output operations and manipulators like setw, respectively.
The statement using namespace std; is used to avoid writing std:: before standard C++ library functions and objects.
The main() function is the entry point of the program and is called when the program starts.
Two integer variables i and j are declared to be used in the loops.
The outer loop runs from i=5 to i>=1, with the decrement of i after each iteration.
The first inner loop (for(j=1; j<i; j++)) is responsible for printing spaces to create an indentation pattern. The number of spaces printed decreases with each iteration of the outer loop, from j=1 to j<i.
The second inner loop (for(j=5; j>=i; j--)) is responsible for printing the numbers in reverse order, from 5 to i. It uses the setw manipulator to ensure each printed number occupies two spaces, which helps in aligning the output.
After printing the spaces and the numbers for each i in the outer loop, the program moves to a new line using cout << "\n";.
The above process repeats until the outer loop condition (i>=1) becomes false.
Once the loops are finished, the main() function returns 0, indicating successful execution 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.
