Example: Floyd's Triangle Generator in C++

// Floyd's Triangle Generator
#include <iostream>

int main() {
    // Step 1: Declare variables for number of rows and the counter.
    int numRows;
    int currentNumber = 1;

    // Step 2: Prompt user for input and read the number of rows.
    std::cout << "Enter the number of rows for Floyd's Triangle: ";
    std::cin >> numRows;

    // Step 3: Use an outer loop to iterate through each row.
    // The outer loop runs from row 1 up to numRows.
    for (int i = 1; i <= numRows; ++i) {
        // Step 4: Use an inner loop to print numbers for the current row.
        // The inner loop runs 'i' times for the i-th row.
        for (int j = 1; j <= i; ++j) {
            // Step 5: Print the current number followed by a space.
            std::cout << currentNumber << " ";
            // Step 6: Increment the current number for the next print.
            currentNumber++;
        }
        // Step 7: Move to the next line after printing all numbers for the current row.
        std::cout << std::endl;
    }

    return 0;
