This program helps you to learn the fundamental structure and syntax of C++ programming.
#include <iostream>
using namespace std;
int main() {
int rows;
cout << "Enter number of rows: ";
cin >> rows;
for (int i = 1; i <= rows; i++) {
// Print spaces
for (int j = 1; j <= rows - i; j++) {
cout << " ";
}
// Print stars
for (int j = 1; j <= i; j++) {
cout << "* ";
}
cout << endl;
}
return 0;
}Output
Enter number of rows: 5

This pattern requires printing spaces before stars. For row i, we print (rows - i) spaces, then i stars. This creates a left-aligned pyramid. The spaces push the stars to the right, creating the pyramid effect.
