C++ Number Pattern 30

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 = 5; j >= 1; j--) {
      if (j > i)
        cout << " ";
      else
        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 starts by including the necessary header file iostream, which allows us to work with input and output streams in C++.
The using namespace std; line is used to bring all the standard C++ library functions and objects into the current scope, so you don't have to prefix them with std:: when using them in the code.
The main() function is the entry point of the program, where the execution starts.
Two integer variables i and j are declared to be used in the subsequent loops.
The outer for loop is used to iterate from i = 1 to i = 5. It will run 5 times since the condition i <= 5 is true for i values 1 to 5.
Inside the outer loop, there's an inner for loop with variable j initialized to 5, and it decrements j from 5 to 1 in each iteration.
Within the inner loop, there is an if statement to check if j is greater than i. If it is true, it prints a space character " ", which effectively creates a space in the output.
If the condition in the if statement is false (i.e., j is less than or equal to i), it prints the value of j. This will be the numbers from 5 down to i.
After the inner loop finishes executing, there is a cout << "\n"; statement that prints a newline character, which moves the cursor to the next line for the next iteration of the outer loop.
The outer loop repeats its iterations until i becomes 6, and then the program exits the loop.
The return 0; statement indicates that the main() function is finished executing, and the program ends. The value 0 is returned to the operating system, signifying that the program executed without any errors.

💯 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.
