C++ Number Pattern 5

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 = 1; 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 by including the necessary header file iostream, which provides input/output operations in C++.
The line using namespace std; allows you to use names from the std namespace without explicitly specifying it. This is done to avoid writing std:: before standard library functions.
The int main() function is the entry point of the program. It is required in every C++ program and serves as the starting point of execution.
Inside the main() function, two integer variables i and j are declared without any initial values.
The outer for loop is used to iterate from i=1 to i<=5, incrementing i by 1 in each iteration.
Inside the outer for loop, there is an inner for loop. This loop is used to print the numbers from 1 to i on a single line.
The inner for loop starts with j=1 and continues until j<=i, incrementing j by 1 in each iteration.
Inside the inner for loop, the statement cout << j; is used to print the value of j on the console.
After the inner for loop completes, a cout << "\n"; statement is used to print a newline character, which moves the cursor to the next line.
The outer for loop continues its iterations until i reaches 5.
Once the outer for loop completes, the return 0; statement is used to indicate a successful termination of the main() function and the program as a whole.

💯 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.
