C++ Number Pattern 52

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, m;
  for (i = 1; i <= 5; i++) {
    m = i;
    for (j = 1; j <= i; j++)
      cout << m++;
    m = m - 2;
    for (k = 1; k < i; k++)
      cout << m--;
    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 provides input and output streams. It also uses the using namespace std; statement to avoid having to type std:: before standard library objects.
The main() function is the starting point of the program.
Four integer variables are declared: i, j, k, and m. These variables will be used in the subsequent loops.
The outer for loop runs from i=1 to i<=5, with i starting at 1 and incrementing by 1 in each iteration. This loop controls the rows of the pattern that will be printed.
Inside the outer loop, the variable m is set equal to i. This is because we want to print numbers starting from i in each row.
The first inner for loop (for(j=1; j<=i; j++)) is responsible for printing the increasing sequence of numbers in the pattern. It runs from j=1 to j<=i, with j starting at 1 and incrementing by 1 in each iteration. The loop prints the value of m and then increments m for the next iteration.
After the first inner loop, the value of m is decremented by 2 (m = m - 2). This prepares m for the next inner loop to print the decreasing sequence of numbers.
The second inner for loop (for(k=1; k<i; k++)) is responsible for printing the decreasing sequence of numbers. It runs from k=1 to k<i, with k starting at 1 and incrementing by 1 in each iteration. The loop prints the value of m and then decrements m for the next iteration.
After both inner loops have finished, a newline character is printed (cout << "\n";). This moves the output to the next line, creating the pattern effect.
The outer loop continues until i becomes 6, at which point it exits, and the program returns 0 to the operating system, indicating successful execution.

💯 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.
