C++ Number Pattern 49

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 <= 10; i++) {
    for (j = 1; j <= i; j++)
      cout << j * i << " ";
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

When you run the above program, it will print the following output:

Output

1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36
7 14 21 28 35 42 49
8 16 24 32 40 48 56 64
9 18 27 36 45 54 63 72 81
10 20 30 40 50 60 70 80 90 100

🧠 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 functionality for input and output operations in C++.
The statement using namespace std; is used to bring all the standard C++ library functions (e.g., cout, cin) into the current scope, so you don't need to prefix them with std::.
The main function is the entry point of the program and is executed first when the program runs. It returns an integer value (usually 0) to indicate the program's completion status to the operating system.
Inside the main function, two integer variables i and j are declared without initialization.
The outer for loop runs from i = 1 to i <= 10 with an increment of i++. This loop iterates 10 times, starting from 1 and ending at 10.
Inside the outer loop, there is another nested for loop. This inner loop runs from j = 1 to j <= i with an increment of j++. The number of iterations in the inner loop depends on the current value of i in the outer loop.
Within the inner loop, the statement cout << j * i << " "; is executed. It prints the product of i and j followed by a space to the standard output (usually the console).
After the inner loop completes its iterations, the cout << "\n"; statement is executed. This prints a new line, causing the next set of values to be printed on a new line in the output.
The outer loop continues its iterations, and the process is repeated until i reaches 10.
Finally, the return 0; statement is encountered, which signals that the program has executed successfully and returns the integer value 0 to the operating system.

💯 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.
