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.
  C++

  // C++ program to print alphabets
  #include <iostream>
  using namespace std;
  
  // Function to print the alphabet
  // in lower case
  void lowercaseAlphabets()
  {
      // lowercase
  
      for (int c = 97; c <= 122; ++c)
          cout << c << " ";
  
      cout << endl;
  }
  // Function to print the alphabet
  // in upper case
  void uppercaseAlphabets()
  {
  
      // uppercase
      for (int c = 65; c <= 90; ++c)
          cout << c << " ";
  
      cout << endl;
  }
  
  // Driver code
  int main()
  {
  
      cout << "Uppercase Alphabets" << endl;
      uppercaseAlphabets(ch);
  
      cout << "Lowercase Alphabets " << endl;
      lowercaseAlphabets(ch);
  
      return 0;
  }

  C

  // C program to print alphabets
  #include <stdio.h>
  
  // Function to print the alphabet
  // in lower case
  void lowercaseAlphabets()
  {
      // for lowercase
      for (int c = 97; c <= 122; ++c)
          printf("%c ", c);
      printf("\n");
  }
  // Function to print the alphabet
  // in upper case
  void uppercaseAlphabets()
  {
  
      // Run a loop from 65 to 90
      for (int c = 65; c <= 90; ++c)
  
          // print its ascii values
          printf("%c ", c);
  
      printf("\n");
  }
  
  // Driver program
  int main()
  {
  
      printf("Uppercase Alphabets\n");
      uppercaseAlphabets();
  
      printf("Lowercase Alphabets\n");
      lowercaseAlphabets();
  
      return 0;
  }

  Java

  // JAVA program to print alphabet
  class Alpha {
      private int ch;
  
      void uppercaseAlphabets()
      {
  
          // uppercase
          for (int c = 65; c <= 90; ++c)
              System.out.print(" " + c);
  
          System.out.print("\n");
      }
      void lowercaseAlphabets()
      {
  
          // lowercase
          for (int c = 97; c <= 122; ++c)
              System.out.print(" " + c);
  
          System.out.print("\n");
      }

      public static void main(String[] args)

          Alpha ob = new Alpha();
          ob.uppercaseAlphabets();
  
          System.out.println("Lowercase Alphabets ");
          ob.lowercaseAlphabets();
      }
  }

• Using alphabets directly i.e.
  • For lowercase alphabets – Run a loop from ‘a’ to ‘z’
  • For uppercase characters – Run a loop from ‘A’ to ‘Z’
