C++ Number Pattern 57

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 = 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:

🧠 How the Program Works

Let's break down the logic behind the code:

The program includes the necessary header file iostream, which allows input and output operations.
The using namespace std; statement is used to indicate that we want to use the standard namespace in C++, which includes commonly used functions and objects without needing to specify the namespace explicitly.
The main() function is the entry point of the program. It returns an integer value, and in this case, it returns 0 to indicate successful execution.
Inside the main() function, three integer variables i, j, and k are declared to be used as loop counters.
The outer for loop runs from i = 1 to i <= 5, with an increment of 1 for each iteration. This loop controls the row number and prints the pattern for each row.
Inside the outer loop, there are three nested loops:
1. The first nested for loop, with j running from 5 to j >= 1 and decrementing by 1 each time. This loop prints spaces or the value of j based on a condition.
2. The second nested for loop, with k running from 2 to k <= 5 and incrementing by 1 each time. This loop prints spaces or the value of k based on a condition. The combination of these two nested loops prints the left and right halves of the pattern.
Inside each nested loop, there's an if-else statement to determine what to print. It checks whether i is equal to the current value of the loop variable (i.e., j or k). If it's equal, it prints the value of j or k; otherwise, it prints a space.
After the two nested loops, the program prints a newline character "\n", moving to the next line for the next row.
The outer loop repeats the above steps five times, creating a pattern in the output.

💯 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.
