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:

Program to display all alphabets from A to Z in uppercase and lowercase using ASCII values:

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

Below is the implementation:

C++




#include <iostream>
using namespace std;
 
// Function to print the alphabet in lower case
void lowercaseAlphabets()
{
    // lowercase
    for (int c = 97; c <= 122; ++c)
        cout << char(c) << " "; // Convert ASCII value to character
 
    cout << endl;
}
 
// Function to print the alphabet in upper case
void uppercaseAlphabets()
{
    // uppercase
    for (int c = 65; c <= 90; ++c)
        cout << char(c) << " "; // Convert ASCII value to character
 
    cout << endl;
}
 
// Driver code
int main()
{
    cout << "Uppercase Alphabets" << endl;
    uppercaseAlphabets();
 
    cout << "Lowercase Alphabets " << endl;
    lowercaseAlphabets();
 
    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 (char c = 65; c <= 90; ++c)
            System.out.print(" " + c);
 
        System.out.print("\n");
    }
    void lowercaseAlphabets()
    {
 
        // lowercase
        for (char c = 97; c <= 122; ++c)
            System.out.print(" " + c);
 
        System.out.print("\n");
    }
 
    // Driver program
    public static void main(String[] args)
    {
        int ch;
        System.out.println("Uppercase Alphabets");
        Alpha ob = new Alpha();
        ob.uppercaseAlphabets();
 
        System.out.println("Lowercase Alphabets ");
        ob.lowercaseAlphabets();
    }
}


Javascript




// Javascript code addition
 
// Function to print the alphabet
// in lower case
function lowercaseAlphabets() {
  // lowercase
  for (let c = 97; c <= 122; ++c) {
    process.stdout.write(String.fromCharCode(c) + " ");
  }
  console.log();
}
 
// Function to print the alphabet
// in upper case
function uppercaseAlphabets() {
  // uppercase
  for (let c = 65; c <= 90; ++c) {
    process.stdout.write(String.fromCharCode(c) + " ");
  }
  console.log();
}
 
// Driver code
console.log("Uppercase Alphabets");
uppercaseAlphabets();
 
console.log("Lowercase Alphabets");
lowercaseAlphabets();

<?php

        echo chr($c)." ";
 
    echo "\n";
}
 
// Function to print the alphabet

Python3




# Python3 program to print alphabets
 
# Function to print the alphabet
# in lower case
def lowercaseAlphabets():
 
    # lowercase
    for c in range(97, 123):
        print(chr(c), end = " ");

# Function to print the alphabet

Output

Uppercase Alphabets
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 
Lowercase Alphabets 
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 

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

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

Below is the implementation:

C++




// C++ program to print alphabets
#include <iostream>
using namespace std;
 
// Function to print the alphabet
// in lower case
void lowercaseAlphabets()

    // lowercase
 
    for (char c = 'a'; c <= 'z'; ++c)
        cout << c << " ";
 
    cout << endl;
}
// Function to print the alphabet
// in upper case
void uppercaseAlphabets()
{
 
    // uppercase
    for (char c = 'A'; c <= 'Z'; ++c)
        cout << c << " ";
 
    cout << endl;
}
 
// Driver code
int main()
{
 
    cout << "Uppercase Alphabets" << endl;
    uppercaseAlphabets();
 
    cout << "Lowercase Alphabets " << endl;
    lowercaseAlphabets();
 
    return 0;
}

    printf("\n");
}
// Function to print the alphabet

    }
    console.log("\n");
  }
   
  lowercaseAlphabets() {

PHP

    // uppercase
    for ($c = ord('A'); $c <= ord('Z'); ++$c)
        echo(" ".chr($c));
 
    echo("\n");

Python3




# Python code yoto print alphabets
 
# Function to print
# lowercase letters
import string
 
def lowercase_alphabets():
    # lowercase characters
     
    # ascii_lowercase holds all the lowercase alphabets
    # so we are basically iterating over them directly
    for i in string.ascii_lowercase:
        print(i,end=" ")
    print()
 
def uppercase_alphabets():
    # uppercase characters
     
    # ascii_uppercase holds all the uppercase alphabets
    # so we are basically iterating over them directly
    for j in string.ascii_uppercase:
        print(j, end=" ")
 
         
print("Uppercase Alphabets are : ")
uppercase_alphabets()
 
print("\nLowercase Alphabets are : ")
lowercase_alphabets()


Output

Uppercase Alphabets
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 
Lowercase Alphabets 
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 

These programs print all alphabets in uppercase and lowercase continuously.
