C++ Number Pattern 24

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;
  k = 1;
  for (i = 1; i <= 5; i += 2) {
    for (j = 5; j >= 1; j--) {
      if (j > i)
        cout << " ";
      else
        cout << k++ << " ";
    }
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

Output

    1 
  2 3 4
5 6 7 8 9

🧠 How the Program Works

Let's break down the logic behind the code:

The program begins by including the necessary header file iostream which provides input/output operations in C++.
The using namespace std; statement allows the program to use names from the std namespace without explicitly specifying it. This means you don't have to write std::cout and std::endl later in the program.
The main() function is the entry point of the program. It has a return type of int.
Inside the main() function, three integer variables i, j, and k are declared.
The variable k is assigned the value of 1.
The program enters a for loop with the variable i initialized to 1, the loop condition i<=5, and the loop increment i+=2. This loop will run three times.
Inside the outer for loop, there is another for loop with the variable j initialized to 5, the loop condition j>=1, and the loop decrement j--. This loop will run five times.
Inside the inner for loop, there is an if statement that checks if j is greater than i.
If j is greater than i, a space character is printed using cout << " ";
If the if condition is not true (i.e., j is not greater than i), the else block is executed. In this case, the value of k is printed using cout << k++ << " ";. The variable k is then incremented by 1.
After the inner for loop finishes, a newline character is printed using cout << "\n";. This moves the output to the next line.
The outer for loop repeats steps 7-11 until the loop condition i<=5 is no longer satisfied.
Once the outer for loop finishes, the program reaches the return 0; statement, which indicates that the program execution was successful, and the program terminates.

💯 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.
