C++ Number Pattern 53

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, k;
  for (i = 1; i <= 5; i++) {
    for (j = 1; j <= 5; j++) {
      if (i == j)
        cout << j;
      else
        cout << " ";
    }
    for (k = 4; k >= 1; k--) {
      if (i == k)
        cout << k;
      else
        cout << " ";
    }
    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:

The #include <iostream> line includes the input/output stream library, which provides functionality for input and output operations.
The using namespace std; line allows us to use elements from the standard C++ library without explicitly qualifying them with the std:: prefix.
The int main() function is the starting point of the program and is required in every C++ program. It returns an integer value to the operating system indicating the exit status of the program (0 for success, non-zero for failure).
Inside the main function, three integer variables i, j, and k are declared without initialization.
The program then enters a nested loop structure. The outer loop (for(i=1; i<=5; i++)) runs from i=1 to i=5, inclusive.
Within the outer loop, there are two inner loops:
1. The first inner loop (for(j=1; j<=5; j++)) runs from j=1 to j=5, inclusive.
2. The second inner loop (for(k=4; k>=1; k--)) runs from k=4 to k=1, inclusive.
Inside the first inner loop, there's an if statement: if(i == j). This condition checks if the value of i is equal to the value of j.
If i is equal to j, then it prints the value of j using cout << j;.
If i is not equal to j, it prints a single space character using cout << " ";.
After the first inner loop is completed, there is a space printed between the first and second inner loops to separate the output.
If i is not equal to j, it prints a single space character using cout << " ";.
Inside the second inner loop, there's another if statement: if(i == k). This condition checks if the value of i is equal to the value of k.
If i is equal to k, then it prints the value of k using cout << k;.
If i is not equal to k, it prints a single space character using cout << " ";.
After both inner loops are completed, a newline character cout << "\n"; is printed to move to the next line before the next iteration of the outer loop starts.
Steps 6 to 14 are repeated until the outer loop completes its 5 iterations.

💯 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.
