C++ Number Pattern 56

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, n;
  for (i = 1; i <= 5; i++) {
    for (j = 5; j >= i; j--)
      cout << "  ";
    for (k = 1; k <= i; k++)
      cout << k << " ";
    n = k - 1;
    for (m = 1; m < i; m++)
      cout << --n << " ";
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

Output

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

🧠 How the Program Works

Let's break down the logic behind the code:

The program includes the necessary header file <iostream>: to enable input and output streams.
The using namespace std; line indicates that we will be using the standard namespace, which contains common C++ functions and objects.
The main() function is the entry point of the program, where execution begins.
Several integer variables i, j, k, m, and n are declared to be used later in the program.
The first outer loop for(i=1; i<=5; i++) runs from i = 1 to i = 5. This loop controls the rows of the output pattern.
The second inner loop for(j=5; j>=i; j--) is used to print spaces before the numbers in each row. The number of spaces printed decreases with the value of i, so that the numbers are right-aligned in the output.
The third inner loop for(k=1; k<=i; k++) is used to print the increasing sequence of numbers from 1 to i, separated by a space.
After the third loop, n is set to the value of k - 1. Since the loop has already run k times and k has been incremented after the loop, we subtract 1 to get the correct value for n.
The fourth inner loop for(m=1; m<i; m++) is used to print the decreasing sequence of numbers from n to 1, separated by a space.
After printing the first row, a newline character cout << "\n"; is printed to move to the next line for the next row.
Steps 6 to 10 are repeated for the remaining rows (i values from 2 to 5).
The return 0; statement indicates the successful termination of the main() function.

💯 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.
