To print an Hourglass Pattern in C++, we use nested loops. The outer loop controls the rows, and the inner loops control the spaces and stars (*) to form the pattern.
In this example,
print_hourglass
that takes the desired number of rows n
as a parameter.for
loops, where the outer loop runs from n
to 1 and the inner loops control the spaces and stars in each row.#include <iostream>
void print_hourglass(int n) {
for (int i = n; i >= 1; i--) {
std::cout << std::string(n - i, ' ') << std::string(2 * i - 1, '*') << '\n';
}
for (int i = 2; i <= n; i++) {
std::cout << std::string(n - i, ' ') << std::string(2 * i - 1, '*') << '\n';
}
}
int main() {
print_hourglass(5);
return 0;
}
