C++ Number Pattern 40

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 <= 5; i++) {
    for (j = i; j <= 5; j++) {
      if (i % 2 == 0)
        cout << "0";
      else
        cout << "1";
    }
    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 to enable input and output stream functionalities.
The line using namespace std; is used to indicate that the program will use the standard C++ namespace, which includes functions like cout and cin for input/output operations.
The main() function is the entry point of the program. It is the starting point of execution for any C++ program.
Two integer variables i and j are declared in the program.
The outer loop for(i=1; i<=5; i++) starts with i initialized to 1, runs as long as i is less than or equal to 5, and increments i by 1 in each iteration.
The inner loop for(j=i; j<=5; j++) starts with j initialized to the current value of i. It runs as long as j is less than or equal to 5, and increments j by 1 in each iteration.
Within the inner loop, there is an if-else condition: if(i%2 == 0). This checks whether the current value of i is even or not. The % operator is the modulo operator, and it gives the remainder when i is divided by 2. If i is even, the condition evaluates to true, and the block of code inside the if block executes.
If i is even, the program prints "0" using cout << "0";. If i is odd, the program prints "1" using cout << "1";.
After the inner loop finishes, a new line is printed using cout << "\n";, moving to the next line for the next iteration of the outer loop.
The outer loop continues to the next iteration, and the value of i is incremented.
The outer loop and inner loop continue until all iterations are completed for both i and j.
Once all iterations are completed, the main() function returns 0, indicating a successful execution of the program.

💯 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.
