C++ Number Pattern 46

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;
  int k = 5;
  for (i = k; i >= 1; i--) {
    for (j = k; j >= 1; j--) {
      if (j > i)
        cout << j << " ";
      else
        cout << i << " ";
    }
    for (j = 2; j <= k; j++) {
      if (j > i)
        cout << j << " ";
      else
        cout << i << " ";
    }
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

Output

5 5 5 5 5 5 5 5 5
5 4 4 4 4 4 4 4 5
5 4 3 3 3 3 3 4 5
5 4 3 2 2 2 3 4 5
5 4 3 2 1 2 3 4 5

🧠 How the Program Works

Let's break down the logic behind the code:

The program includes the necessary header file <iostream> which allows it to use input/output streams like cout and cin.
The using namespace std; line means that you can use standard C++ library functions and objects directly without having to specify the std:: prefix.
The main() function is the entry point of the program.
Two integer variables i and j are declared, which will be used as loop counters.
An integer variable k is declared and initialized with the value 5.
The first for loop runs from k (5 in this case) to 1 in reverse (decrementing i from k to 1).
Inside the first loop, there are two nested for loops.
The first nested for loop runs from k to 1 in reverse (decrementing j from k to 1).
In the first nested loop, there's an if-else condition. If j > i, it will print the value of j, followed by a space. Otherwise, it will print the value of i, followed by a space.
After the first nested loop, there's another nested for loop that runs from 2 to k (incrementing j from 2 to k).
In the second nested loop, there's again an if-else condition. If j > i, it will print the value of j, followed by a space. Otherwise, it will print the value of i, followed by a space.
After the second nested loop, there's a cout << "\n"; statement, which adds a new line to separate each row of the pattern.
The first for loop continues until i becomes 1, and the pattern is printed for each value of i from k to 1.
Finally, the return 0; statement indicates that the program has completed successfully, and the main() function returns an integer value 0.

💯 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.
