C++ Number Pattern 15

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 >= 1; j--)
      cout << j % 2;
    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 with including the necessary header file <iostream>, which allows us to use input/output stream functionalities.
The using namespace std; statement is used to avoid writing std:: before standard library functions and objects. It means that we can directly use cout instead of std::cout.
The main() function is the entry point of the program.
Two integer variables i and j are declared to be used as loop counters.
The first for loop runs from i=1 to i<=5, incrementing i by 1 in each iteration. This outer loop controls the number of rows to be printed, which will be 5 in this case.
Inside the outer loop, there's another nested for loop with j=i as the initial value. This inner loop controls the number of digits to be printed in each row.
The inner loop runs as long as j is greater than or equal to 1, and in each iteration, it decrements j by 1.
Inside the inner loop, the program prints the value of j%2. The % operator calculates the remainder of the division, and since we are using j%2, it will either be 0 or 1. This results in alternating 0s and 1s being printed.
After the inner loop, a newline character "\n" is printed to move to the next line.
The outer loop continues for the next iteration, and the process is repeated until i becomes greater than 5.
Once the outer loop finishes, the return 0; statement is encountered, and the main() function returns an integer value of 0 to indicate successful program execution.

💯 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.
