C++ Number Pattern 47

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;
  // First Part 
  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";
  }
  // Second Part
  for (i = 2; i <= k; 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
5 4 3 2 2 2 3 4 5
5 4 3 3 3 3 3 4 5
5 4 4 4 4 4 4 4 5
5 5 5 5 5 5 5 5 5

🧠 How the Program Works

Let's break down the logic behind the code:

The program includes the necessary header file iostream for input/output stream handling.
The using namespace std; statement is used to indicate that we are using the standard C++ namespace, so we don't need to write std:: before standard library elements like cout and endl
The main() function is the starting point of the program.
Two integer variables i and j are declared to be used in loops, and an integer variable k is initialized with the value 5.
The first part of the program starts with a nested loop for generating the upper half of the pattern.
- The outer loop runs from k to 1, decrementing the value of i in each iteration.
- The first inner loop runs from k to 1, decrementing the value of j in each iteration.
- In the first inner loop, if j is greater than i, it prints the value of j followed by a space.
- Otherwise, it prints the value of i followed by a space.
- Then, a second inner loop runs from 2 to k, incrementing the value of j in each iteration.
- In the second inner loop, if j is greater than i, it prints the value of j followed by a space.
- Otherwise, it prints the value of i followed by a space.
- After printing the pattern for a particular i, a new line is added.
The second part of the program starts with another nested loop for generating the lower half of the pattern.
- The outer loop runs from 2 to k, incrementing the value of i in each iteration.
- The first inner loop runs from k to 1
- In the first inner loop, if j is greater than i, it prints the value of j followed by a space.
- Otherwise, it prints the value of i followed by a space.
- Then, a second inner loop runs from 2 to k, incrementing the value of j in each iteration.
- In the second inner loop, if j is greater than i, it prints the value of j followed by a space.
- Otherwise, it prints the value of i followed by a space.
- After printing the pattern for a particular i, a new line is added.
Finally, 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.
