Write a C++ program to print pyramid alphabets pattern using for loop.
#include<iostream> using namespace std; int main() { int rows; cout << "Enter Pyramid of Alphabets Rows = "; cin >> rows; cout << "Printing Pyramid Alphabets Pattern\n"; int alphabet = 64; for (int i = 1; i <= rows; i++) { for (int j = 1; j <= rows - i; j++) { cout << " "; } for (int k = i; k > 0; k--) { cout << char(alphabet + k); } for (int l = 2; l <= i; l++) { cout << char(alphabet + l); } cout << "\n"; } }
This example program prints the pyramid pattern of alphabets using a while loop.
#include<iostream> using namespace std; int main() { int rows, i, j, k, l, alphabet; cout << "Enter Pyramid of Alphabets Rows = "; cin >> rows; cout << "Printing Pyramid Alphabets Pattern\n"; alphabet = 64; i = 1; while (i <= rows) { j = 1; while (j <= rows - i) { cout << " "; j++; } k = i; while (k > 0) { cout << char(alphabet + k); k--; } l = 2; while (l <= i) { cout << char(alphabet + l); l++; } cout << "\n"; i++; } }
Enter Pyramid of Alphabets Rows = 15
