Recommended: Please try your approach on {IDE} first, before moving on to the solution.

C++

// CPP program to print alphabet A pattern 
#include <iostream> 
using namespace std; 
  
// Function to display alphabet pattern 
void display(int n) 
{ 
    // Outer for loop for number of lines 
    for (int i = 0; i < n; i++) { 
  
        // Inner for loop for logic execution 
        for (int j = 0; j <= n / 2; j++) { 
  
            // prints two column lines 
            if ((j == 0 || j == n / 2) && i != 0 || 
  
                // print first line of alphabet 
                i == 0 && j != 0 && j != n / 2 || 
  
                // prints middle line 
                i == n / 2) 
                cout << "*"; 
            else
                cout << " "; 
        } 
  
        cout << '\n'; 
    } 
} 
// Driver Function 
int main()

                    // prints middle line 
                    i == n / 2) 
  
                    System.out.print("*"); 
                else
                    System.out.print(" "); 
            }
