C++ Number Pattern 25

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 = i; j <= 5; j++) {
      if (i < 4)
        cout << i;
      else
        cout << 6 - i;
    }
    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 begins with including the necessary header file iostream, which provides input/output stream functionality.
The using namespace std; statement allows you to use names from the std namespace directly, without needing to prefix them with std::.
The int main() function is the starting point of the program.
Two integer variables, i and j, are declared. These variables will be used as loop counters.
The outer for loop initializes i to 1 and continues as long as i is less than or equal to 5. It increments i by 1 in each iteration.
Inside the outer loop, there is another nested for loop that initializes j to the value of i and continues as long as j is less than or equal to 5. It also increments j by 1 in each iteration.
Inside the nested for loop, there is an if-else statement. If the value of i is less than 4, it executes the cout << i; statement, which prints the value of i. Otherwise, if the value of i is 4 or 5, it executes the cout << 6 - i; statement, which prints the result of subtracting i from 6.
After printing the appropriate value based on the condition, the program goes back to the nested for loop and continues until the condition becomes false.
After the nested for loop completes, the program moves to the next line by executing cout << "\n";, which prints a newline character to create a new line.
The outer for loop continues to the next iteration, and the process is repeated until i becomes 6, which is when the outer for loop terminates.
Finally, the return 0; statement is executed, indicating that the program has finished executing and returns the value 0 to the operating system, indicating successful execution.

💯 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.
