C++ Number Pattern 4

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 >= 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 starts with including the necessary header file iostream which allows input/output operations in C++.
The line using namespace std; brings the std namespace into the current scope, which means we can directly use standard library functions without specifying the std:: prefix.
The main() function is the entry point of the program. It is where the execution of the program begins and ends.
Two integer variables i and j are declared to be used in the following loops.
The outer loop for(i=1; i<=5; i++) is responsible for controlling the number of rows in the output. It starts with i equal to 1 and continues until i is less than or equal to 5. The loop increments i by 1 in each iteration.
Inside the outer loop, there is an inner loop for(j=5; j>=i; j--). This loop controls the number of columns and prints the values of j. It starts with j equal to 5 and continues until j is greater than or equal to i. The loop decrements j by 1 in each iteration.
Within the inner loop, the statement cout << j; prints the current value of j on the console.
After the inner loop finishes, the statement cout << "\n"; is executed, which outputs a newline character to move to the next line.
The outer loop continues until i becomes greater than 5, and for each iteration, the inner loop prints a decreasing sequence of numbers.
Finally, the program reaches the return 0; statement, which indicates successful termination of the main() function and returns the value 0 to the operating system, indicating that the program ran 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.
