Program to display all alphabets from A to Z in uppercase and lowercase both

Alphabets in lowercase and uppercase can be printed using two methods, first is using ASCII values and second is to directly print values from ‘A’ to ‘Z’ using loops. Below are the implementation of both methods:

  • Using ASCII values:
    • ASCII value of uppercase alphabets – 65 to 90.
    • ASCII value of lowercase alphabets – 97 to 122.

    a b c d e f g h i j k l m n o p q r s t u v w x y z 
    
  • Using alphabets directly i.e.



    • For lowercase alphabets – Run a loop from ‘a’ to ‘z’
    • For uppercase characetrs – Run a loop from ‘A’ to ‘Z’
