C++ Number Pattern 44

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 = i; j < 5; j++)
      cout << " ";
    for (k = 1; k < i * 2; k++)
      cout << k;
    cout << "\n";
  }
  for (i = 4; i >= 1; i--) {
    for (j = 5; j > i; j--)
      cout << " ";
    for (k = 1; k < i * 2; k++)
      cout << k;
    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 functionalities.
The using namespace std; line allows us to use the standard namespace without prefixing each statement with std::.
The main() function is the entry point of the program.
The variables i, j, and k are declared to be of type int. These variables will be used as loop counters.
The first for loop is used to control the outer loop, which iterates from i = 1 to i <= 5. This loop is responsible for printing the upper half of the pyramid.
Inside the first loop, there are three nested loops.
The second for loop (j) is used to print spaces before the numbers in each row. It starts with j = i and continues until j < 5.
The third for loop (k) is used to print the numbers in each row. It starts with k = 1 and continues until k < i * 2. The value of i * 2 determines the number of digits to be printed in each row.
After printing the spaces and numbers, cout << "\n"; is used to move to the next line.
The second for loop is used to print the lower half of the pyramid. It iterates from i = 4 to i >= 1.
Inside the second loop, there are similar nested loops to print the spaces and numbers, but the conditions of the loops are reversed compared to the first loop.
Finally, return 0; is used to exit the main() function and indicate that the program executed 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.
