C++ Number Pattern 13

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;
  for (i = 5; i >= 1; i--) {
    if (i % 2 == 0) {
      for (j = i; j >= 1; j--)
        cout << j;
    } else {
      for (j = 1; j <= i; j++)
        cout << j;
    }
    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 starts by including the necessary header file <iostream>, which allows input/output operations in C++. The using namespace std; statement is used to avoid typing std:: before every standard library object.
The main() function is the entry point of the program. It has a return type of int, indicating that it should return an integer value.
Two integer variables i and j are declared to be used in the program.
The for loop is used to iterate from i=5 to i>=1, with i-- decrementing i by 1 in each iteration.
Inside the for loop, there is an if statement that checks if i is divisible by 2 (i.e., if i is an even number). If the condition i%2 == 0 evaluates to true, the following block of code executes:

a. Another for loop is used, starting with j=i and decrementing j by 1 in each iteration until j>=1.
b. Inside this loop, the value of j is printed using the cout statement. This prints the current value of j on the console.

If the if condition in step 5 evaluates to false (i.e., i is an odd number), the following block of code executes:
- a. Another for loop is used, starting with j=1 and incrementing j by 1 in each iteration until j<=i.
- b. Inside this loop, the value of j is printed using the cout statement. This prints the current value of j on the console.
After printing the numbers based on the value of i, a newline character "\n" is printed using cout to move to the next line.
The program continues to the next iteration of the outer for loop until i reaches 1.
Once the outer for loop completes, the program reaches the return 0; statement, indicating that the program executed successfully and is returning an integer value of 0 to the operating system.

💯 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.
