C++ Number Pattern 58

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;
  // First Part 
  for (i = 1; i <= 5; i++) {
    for (j = 5; j >= 1; j--) {
      if (i == j)
        cout << j;
      else
        cout << " ";
    }
    for (k = 2; k <= 5; k++) {
      if (i == k)
        cout << k;
      else
        cout << " ";
    }
    cout << "\n";
  }
  // Second Part
  for (i = 4; i >= 1; i--) {
    for (j = 5; j >= 1; j--) {
      if (i == j)
        cout << j;
      else
        cout << " ";
    }
    for (k = 2; k <= 5; k++) {
      if (i == k)
        cout << k;
      else
        cout << " ";
    }
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

Output

🧠 How the Program Works

Let's break down the logic behind the code:

The program includes the necessary header file iostream to work with input and output streams and declares that it will use the std namespace.
The main() function is defined, which is the entry point of the C++ program.
Three integer variables i, j, and k are declared to be used in loops.
First Part:
- The first part consists of an outer loop with i ranging from 1 to 5 (inclusive).
- There are three nested loops within this part.
- The first nested loop, with j ranging from 5 to 1 (inclusive), is responsible for printing the numbers from 5 to i and spaces otherwise. This creates a reverse diagonal pattern.
- The second nested loop, with k ranging from 2 to 5 (inclusive), is responsible for printing the numbers from i to 5 and spaces otherwise. This creates a diagonal pattern.
- After each line of numbers is printed, a newline character '\n' is added to move to the next line.
Second Part:
- The second part is similar to the first part, but it prints the pattern in reverse. The outer loop now ranges from 4 to 1 (inclusive).
- This second part creates a mirrored version of the pattern printed in the first part.
Finally, the return 0; statement is used to indicate that the program has completed successfully.

💯 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.
