C++ Pyramid Program Program
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;
// Full Pyramid
cout << "\nFull Pyramid:" << endl;
for (int i = 1; i <= rows; i++) {
for (int j = 1; j <= rows - i; j++) {
cout << " ";
}
for (int j = 1; j <= 2 * i - 1; j++) {
cout << "*";
}
cout << endl;
}
// Inverted Pyramid
cout << "\nInverted Pyramid:" << endl;
for (int i = rows; i >= 1; i--) {
for (int j = 1; j <= rows - i; j++) {
cout << " ";
}
for (int j = 1; j <= 2 * i - 1; j++) {
cout << "*";
}
cout << endl;
}
// Hollow Pyramid
cout << "\nHollow Pyramid:" << endl;
for (int i = 1; i <= rows; i++) {
for (int j = 1; j <= rows - i; j++) {
cout << " ";
}
for (int j = 1; j <= 2 * i - 1; j++) {
if (j == 1 || j == 2 * i - 1 || i == rows) {
cout << "*";
} else {
cout << " ";
}
}
cout << endl;
}
return 0;
}Output
Enter number of rows: 5

*********Understanding Pyramid Program
This program demonstrates 10 different pyramid patterns: full pyramid, inverted pyramid, hollow pyramid, number pyramid, alphabet pyramid, Floyd's pyramid, Pascal's pyramid, and various combinations.
Note: To write and run C++ programs, you need to set up the local environment on your computer. Refer to the complete article Setting up C++ Development Environment. If you do not want to set up the local environment on your computer, you can also use online IDE to write and run your C++ programs.
