Write a C++ program to print inverted triangle alphabets pattern using for loop.
#include<iostream> using namespace std; int main() { int rows; cout << "Enter Inverted Triangle of Alphabets Rows = "; cin >> rows; cout << "Inverted Triangle Alphabets Pattern\n"; int alphabet = 65; for (int i = 0; i <= rows - 1; i++) { for (int j = 0; j <= i; j++) { cout << " "; } for (int k = 0; k <= rows - i - 1; k++) { cout << char(alphabet + k) << " "; } cout << "\n"; } }

C++ program to print the inverted triangle alphabets pattern using a while loop.
#include<iostream> using namespace std; int main() { int rows, i, j, k, alphabet; cout << "Enter Inverted Triangle of Alphabets Rows = "; cin >> rows; cout << "Inverted Triangle Alphabets Pattern\n"; alphabet = 65; i = 0; while (i <= rows - 1) { j = 0; while (j <= i) { cout << " "; j++; } k = 0; while (k <= rows - i - 1) { cout << char(alphabet + k) << " "; k++; } cout << "\n"; i++; } }
Enter Inverted Triangle of Alphabets Rows = 15

This C++ example displays the inverted triangle pattern of alphabets using the do while loop.
#include<iostream> using namespace std; int main() { int rows, i, j, k, alphabet; cout << "Enter Inverted Triangle of Alphabets Rows = "; cin >> rows; cout << "Inverted Triangle Alphabets Pattern\n"; alphabet = 65; i = 0; do { j = 0; do { cout << " "; } while (j++ <= i); k = 0; do { cout << char(alphabet + k) << " "; } while (++k <= rows - i - 1); cout << "\n"; } while (++i <= rows - 1); }
Enter Inverted Triangle of Alphabets Rows = 17
