10 Stunning Patterns in C++ You Should Try!

Introduction
Programming is not just about solving problems; it’s also about exploring creativity. Patterns in programming help improve logic-building skills, enhance problem-solving abilities, and make learning enjoyable. This week, I explored 10 exciting patterns using C++ and learned how to implement them step by step. In this blog, I’ll share the journey, along with the code and outputs for each pattern.

Pattern 1: Right-Aligned Triangle with Stars

Code:

#include <iostream>
using namespace std;

int main() {
    for (int i = 1; i <= 5; i++) {
        for (int j = 1; j <= 5; j++) {
            if (j <= 5 - i)
                cout << " ";
            else
                cout << "*";
        }
        cout << endl;
    }
    return 0;
}

Output:

    *
   **
  ***
 ****
*****

Pattern 2: Right-Aligned Triangle with Numbers

Code:

#include <iostream>
using namespace std;

int main() {
    for (int i = 1; i <= 5; i++) {
        for (int j = 1; j <= 5; j++) {
            if (j <= 5 - i)
                cout << " ";
            else
                cout << i;
        }
        cout << endl;
    }
    return 0;
}

Output:

Pattern 3: Incrementing Number Triangle

Code:

#include <iostream>
using namespace std;

int main() {
    for (int i = 1; i <= 5; i++) {
        int num = 1;
        for (int j = 1; j <= 5; j++) {
            if (j <= 5 - i)
                cout << " ";
            else
                cout << num++;
        }
        cout << endl;
    }
    return 0;
}

Output:

Pattern 4: Alphabet Pyramid

Code:

#include <iostream>
using namespace std;

int main() {
    for (int i = 1; i <= 5; i++) {
        char ch = 'A';
        for (int j = 1; j <= 5; j++) {
            if (j <= 5 - i)
                cout << " ";
            else
                cout << ch++;
        }
        cout << endl;
    }
    return 0;
}

Output:

    A
   AB
  ABC
 ABCD
ABCDE

Pattern 5: Pyramid of Stars

Code:

#include <iostream>
using namespace std;

int main() {
    for (int i = 1; i <= 5; i++) {
        for (int j = 1; j <= 5 - i; j++)
            cout << " ";
        for (int j = 1; j <= 2 * i - 1; j++)
            cout << "*";
        cout << endl;
    }
    return 0;
}

Output:

    *
   ***
  *****
 *******
*********

Pattern 6: Inverted Pyramid of Stars

Code:

#include <iostream>
using namespace std;

int main() {
    for (int i = 5; i >= 1; i--) {
        for (int j = 1; j <= 5 - i; j++)
            cout << " ";
        for (int j = 1; j <= 2 * i - 1; j++)
            cout << "*";
        cout << endl;
    }
    return 0;
}

Output:

*********
 *******
  *****
   ***
    *

What I Learned
