This C++ program outputs a pattern in Hourglass shape on the screen. Two nested for loops are needed for this
#include <iostream>
using namespace std;
int main() {
int i, j, k, n = 8;
for (i = 1; i <= n; i++) {
for (j = 1; j < i; j++) {
cout << ' ';
}
for (k = i; k <= n; k++) {
cout << "* ";
}
cout << endl;
}
for (i = n - 1; i >= 1; i--) {
for (j = 1; j < i; j++) {
cout << ' ';
}
for (k = i; k <= n; k++) {
cout << "* ";
}
cout << endl;
}
return 0;
}
