C++ Number Pattern 59

Here`s a program that prints the above number pattern using C++ Programming:

example.cpp

Copied

#include <iostream>
#include <iomanip>
using namespace std;

int main() {
  int i, j;
  int k = 6, l = 13, m = 16;
  for (i = 1; i <= 5; i++) {
    for (j = 1; j <= 5; j++) {
      if (i == 1)
        cout << setw(3) << j;
      else if (j == 5)
        cout << setw(3) << k++;
      else if (i == 5)
        cout << setw(3) << l--;
      else if (j == 1)
        cout << setw(3) << m--;
      else
        cout << "   ";
    }
    cout << "\n";
  }
  return 0;
}

💻 Testing the Program

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

Output

    1  2  3  4  5
    16          6
    15          7
    14          8
    13 12 11 10 9

🧠 How the Program Works

Let's break down the logic behind the code:

The program includes two C++ standard libraries: iostream and iomanip. The iostream library is used for input and output operations, and iomanip is used for formatting the output.
The using namespace std; line brings all the names from the std namespace into the current scope, so you can use names like cout, cin, etc., without explicitly specifying std:: before them.
The main() function is the entry point of the program.
Three integer variables k, l, and m are declared and initialized with the values 6, 13, and 16, respectively.
The program enters a nested for loop. The outer loop runs from i = 1 to i <= 5, and the inner loop runs from j = 1 to j <= 5.
Inside the nested loops, there are conditional statements (if-else) to determine what to print at each position in the 5x5 grid.
If i == 1, it prints the value of j with a width of 3 characters using setw(3). This means the output will be right-aligned and take up 3 characters of space.
If j == 5, it prints the value of k with a width of 3 characters using setw(3) and then increments k by one.
If i == 5, it prints the value of l with a width of 3 characters using setw(3) and then decrements l by one.
If j == 1, it prints the value of m with a width of 3 characters using setw(3) and then decrements m by one.
If none of the above conditions is true (i.e., for all the other positions in the grid), it prints three spaces, creating an empty space.
After each row is printed, the program adds a new line character \n to move to the next row.
The loop continues until all the rows and columns of the 5x5 grid are printed.
Finally, the main() function returns 0, indicating successful program 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.
