Lecture 27:- Solid Half Diamond

A solid half diamond pattern is a pattern where asterisks (*) are arranged in a half diamond shape, and the interior is solid (filled with asterisks). Each row contains a varying number of asterisks, forming the half diamond shape.

Here's an example of a solid half diamond pattern with 5 rows:

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

Let's write a C++ program to generate the solid half diamond pattern based on the number of rows specified by the user:

cppCopy code

#include <iostream> int main() {    int rows;    std::cout << "Enter the number of rows: ";    std::cin >> rows;    // Upper part of the solid half diamond    for (int i = 1; i <= rows; i++) {        for (int j = 1; j <= i; j++) {            std::cout << "*";        }        std::cout << std::endl;    }    // Lower part of the solid half diamond    for (int i = rows - 1; i >= 1; i--) {        for (int j = 1; j <= i; j++) {            std::cout << "*";        }        std::cout << std::endl;    }    return 0; }

Example output for rows = 5:

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

In the code above, we use two nested loops to print the upper and lower parts of the solid half diamond. The outer loop i controls the number of rows, and the inner loop j prints the asterisks in each row. In the upper part, i starts from 1 and goes up to the number of rows specified, printing an increasing number of asterisks in each row. In the lower part, i starts from rows - 1 and goes down to 1, printing a decreasing number of asterisks in each row.

Feel free to experiment with different values of rows to generate solid half diamond patterns of different sizes.
