right side pattern triangle c++

C++ code for right side pattern triangle:

#include <iostream>
using namespace std;

int main() {
    int rows, i, j;

    cout << "Enter number of rows: ";
    cin >> rows;

    for (i = 1; i <= rows; i++) {
        for (j = 1; j <= rows; j++) {
            if (j <= rows - i) {
                cout << " ";
            } else {
                cout << "*";
            }
        }
        cout << endl;
    }

    return 0;
}

Explanation:

• Include necessary libraries: #include <iostream> is used to include the input/output stream library in the program.

• Declare the namespace: using namespace std; is used to avoid writing std:: before standard library objects like cin, cout, etc.

• Main function: The main() function is the entry point of the program.

• Declare variables: int rows, i, j; declares the variables for the number of rows and the loop iterators.

• Input: cout << "Enter number of rows: "; prompts the user to enter the number of rows, and cin >> rows; stores the input in the variable rows.

• Nested loops: The outer loop runs from i = 1 to rows, and the inner loop runs from j = 1 to rows.

• Print spaces and stars: Based on the condition if (j <= rows - i), spaces or stars are printed to create the right-side pattern triangle.

• Newline: cout << endl; is used to move to the next line after each row is printed.

• Return statement: return 0; indicates successful termination of the program.
