Print the Alphabets A to Z in Star Pattern

Given any alphabet between A to Z, the task is to print the pattern of the given alphabet using star.

Examples:

Input: A
Output: 
    **    
   *  *   
  ******  
 *      * 
*        *

Input: P
Output:
***** 
*    *
***** 
*     
*

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

Approach: The code to print each alphabet is created in a seprate function. Use switch statement to call the desired function on the basis of the alphabet’s pattern required.

Below is the implementation.

C++

// C++ implementation to print the 
// pattern of alphabets A to Z using * 
  
#include <stdio.h> 
  
// Below height and width variable can be used 
// to create a user-defined sized alphabet's pattern 
  
// Number of lines for the alphabet's pattern 
int height = 5; 
// Number of character width in each line 
int width = (2 * height) - 1; 
  
// Function to find the absolute value 
// of a number D 
int abs(int d) 
{ 
    return d < 0 ? -1 * d : d; 
} 
  
// Function to print the pattern of 'A' 
void printA() 
{ 
    int n = width / 2, i, j; 
    for (i = 0; i < height; i++) {

            if (j == n || j == (width - n) 
                || (i == height / 2 && j > n 
                    && j < (width - n))) 
                printf("*");
