C++ Number Pattern 9

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 << i;
    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:

First, the program includes the necessary header file <iostream> which allows input and output operations.
The using namespace std; line tells the compiler to use the std namespace, which contains standard C++ library functions and objects.
The main() function is the entry point of the program. It is where the program execution starts.
Inside the main() function, two integer variables i and j are declared without any initial values.
The first for loop initializes i with 1 and continues as long as i is less than or equal to 5. After each iteration, the value of i is incremented by 1.
Inside the first for loop, there is another nested for loop. The second for loop initializes j with 1 and continues as long as j is less than or equal to the current value of i. After each iteration, the value of j is incremented by 1.
Inside the nested for loop, the statement cout << i; is executed. This prints the current value of i to the console. Since this statement is inside the second for loop, it will be executed i times, printing the value of i on the same line.
After the second for loop, the statement cout << "\n"; is executed. This outputs a newline character, which moves the cursor to the next line, creating a new line after each iteration of the first for loop.
Steps 5-8 are repeated until the condition in the first for loop (i <= 5) becomes false. This means that the entire pattern will be printed five times.
Finally, the return 0; statement ends the main() function and returns the value 0, indicating successful execution of the program.

💯 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.
