Fix the Broken Triangle Printer — C++ Fundamentals

This program tries to print a left-aligned triangle of asterisks, num_rows rows tall, where row 1 has one star, row 2 has two stars, and so on up to num_rows stars in the last row.

Run it with num_rows = 4 and it looks fine. Run it with num_rows = 0 and it prints a row anyway, when it shouldn’t print anything at all.

Find out why, and fix it.

#include <iostream>int main() { int num_rows = 0; // Try changing this to 4, then back to 0 int row = 1; do { for (int col = 1; col <= row; ++col) { std::cout << "*"; } std::cout << "\n"; ++row; } while (row <= num_rows); return 0;}
