C++ Number Pattern 22

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 = 1; i <= 9; i += 2) {
    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 includes the necessary header file <iostream>, which provides input and output stream functionality.
The line using namespace std; allows the program to use the std namespace without explicitly specifying it for each standard library function.
The main() function is the starting point of the program's execution. It returns an integer value indicating the exit status of the program to the operating system (0 in this case, indicating successful execution).
Two integer variables i and j are declared. These variables will be used to control the loops later in the program.
The outer for loop initializes i to 1 and continues as long as i is less than or equal to 9. In each iteration, i is incremented by 2 (i+=2), so i takes the values 1, 3, 5, 7, and 9.
The inner for loop initializes j to 1 and continues as long as j is less than or equal to i. In each iteration, the loop prints the value of j using cout, which is the reason we see a sequence of numbers in each line.
After printing all the numbers in the inner loop, the outer loop executes cout << "\n";, which moves to the next line, creating a new line for the next iteration.
The program continues with the next iteration of the outer loop, repeating the above steps until the condition i <= 9 becomes false.
The return 0; statement signifies the end of the main() function and indicates successful program execution 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.
