C++ Number Pattern 2

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++)
      cout << j;
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

When you run the above program, it will print the following 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 work with input and output streams in C++. The using namespace std; line enables us to use standard C++ library functions and objects without explicitly specifying the std:: namespace prefix.
The main() function is the entry point of the program. It is required in every C++ program, and the execution of the program begins from here.
Two integer variables, i and j, are declared at the beginning of the main() function. These variables will be used in the upcoming for loops.
The first for loop starts with for(i=1; i<=5; i++). This loop runs from i=1 to i=5 (inclusive). It serves as the outer loop.
Inside the outer loop, there's another for loop: for(j=i; j<=5; j++). This inner loop starts with j having the same value as i and runs from j=i to j=5 (inclusive). It serves as the inner loop.
Within the inner loop, the program prints the current value of j using cout << j;. This will print the numbers in a pattern that depends on the value of i.
After the inner loop, the program prints a newline character \n using cout << "\n";. This newline character causes the next output to appear on a new line.
After the completion of the inner loop, the control goes back to the outer loop. The value of i is incremented, and the process repeats until i becomes greater than 5.
When i becomes 6, the outer loop stops, and the main() function returns 0, indicating 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.
