C++ Exercises: Display the pattern like pyramid using the alphabet

C++ For Loop: Exercise-48 with Solution

Write a program in C++ to display the pyramid pattern using the alphabet.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

int main()
{
    int i, j;
    char alph = 'A';
    int n, blk;
    int ctr = 1;
    cout << "\n\n Display the pattern like pyramid using the alphabet:\n";
    cout << "---------------------------------------------------------\n";
    cout << " Input the number of Letters (less than 26) in the Pyramid: ";
    cin >> n;
    for (i = 1; i <= n; i++) {
        for (blk = 1; blk <= n - i; blk++)
            cout << "  ";
        for (j = 0; j <= (ctr / 2); j++) 
        {
            cout << alph++ << " ";
        }
        alph = alph - 2;
        for (j = 0; j < (ctr / 2); j++) 
        {
            cout << alph-- << " ";
        }
        ctr = ctr + 2;
        alph = 'A';
        cout << endl;
    }
}

Sample Output:

 Display the pattern like pyramid using the alphabet:                  
---------------------------------------------------------              
 Input the number of Letters (less than 26) in the Pyramid: 5          
        A                                                              
      A B A                                                            
    A B C B A                                                          
  A B C D C B A                                                        
A B C D E D C B A
