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;

{

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;

# Python code yoto print alphabets # Function to print # lowercase letters import string

# lowercase characters
# ascii_lowercase holds all the lowercase alphabets

# ascii_uppercase holds all the uppercase alphabets
# so we are basically iterating over them directly

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.
