Simple But Interesting Pattern

Logic used by programmer is much more important than syntax of any programming language.
If you really want to build upon your logic for programming - then try to create simple pattern like A, B, other number patterns etc. which really help in developing conditional handling of scenarios.


When I first started programming almost 6 years back, I used to take up different challenging programs to code by myself. So I did code all A to Z patterns, many other number patterns, etc.


Here are code snippets of few patterns -
1)  Pattern of Uppercase Alphabet "A" -


                       **                          Here, User will input Height (and/or width of this pattern)
     *  *                         And program will output, output as shown... 
   *****
  *        *
Code - (its in Java, but can be easily converted for any other programming language)

        /**

  *      **      
        *  *     
       *    *    
      ********   
     *        *  
    *          * 
   *            *
 
 For User input - 7
  
  * @param size
  */
 
 public static void getPatternA(int size){
  for(int i=1;i<=size;i++){
   for(int j=0;j<=(2*size);j++){
    if((j==(i+size)) || (j == (size-(i-1)))){
     System.out.print("*");
    }else if(i==((size/2)+1)){
     if((j>= i) && (j<=(i+size-1))){
      System.out.print("*");
     }else{
      System.out.print(" ");
     }
    }else{
     System.out.print(" ");
    }
   }
   System.out.print("\n");
  }
 }                                                                                

2) Pattern of Uppercase Alphabet "B" -

/**
  * By - Pramod khare
  *   **** 
      *   *
      *   *
      *   *
      **** 
      *   *
      *   *
      *   *
      **** 
 
 For User input - 9
  
  * @param  size - height of pattern */
 
 public static void getPatternB(int size){
  for(int i=1;i<=size;i++){
   for(int j=1;j<=((size/2)+1);j++){
    if((i==1) && (j == ((size/2)+1))){
     System.out.print(" ");
    }else if((i==((size/2)+1)) && (j == ((size/2)+1))){
     System.out.print(" ");
    }else if((i == size) && (j ==((size/2)+1))){
     System.out.print(" ");
    }else{
     if(i == 1 || j ==1 || i == ((size/2)+1) || j == ((size/2)+1) || i == size){
      System.out.print("*");
     }else{
      System.out.print(" ");
     }
    }
   }
   System.out.print("\n");
  }
 }

3) Pattern of Uppercase Alphabet "C" -

/**
  * By - Pramod khare
  *    ***
      *   
      *   
      *   
      *   
       ***
 
 For User input - 6
  
  * @param size - height of pattern
  */
 
 public static void getPatternC(int size){
  for(int i=1;i<=size;i++){
   for(int j=1;j<=((size/2)+1);j++){
    if((i==1 && j ==1) || (i==size && j==1)){
     System.out.print(" ");
    }else if((i == size) || (j == 1) || (i == 1)){
     System.out.print("*");
    }else{
     System.out.print(" ");
    }
   }
   System.out.print("\n");
  }
 }

The same way patterns-programs can be written for lower case letters or symbols or any other shapes, and when its really a fun and a challenge before we complete it.


So go and try out your brain in your free time this way.
