Introduction

In this article, we will be learning the approach to solve this problem of displaying characters from A to Z. 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.

But for this we first need to know the ascii values of these:

  • ASCII value of Uppercase Alphabets: 65 to 90.
  • ASCII value of Lowercase Alphabets: 97 to 122.

Now we will discuss two approaches to accomplish this task:

Method 1: Using ASCII Value

#include <iostream>
using namespace std;
 
// Function to print the alphabet in lowercase
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;
}
int main()
{
 
    cout << "Uppercase Alphabets Are:" << endl;
    uppercaseAlphabets(ch);
 
    cout << "Lowercase Alphabets Are: " << endl;
    lowercaseAlphabets(ch);
 
    return 0;
}

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

Method 2: Using Alphabets Directly

#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(ch);
 
    cout << "Lowercase Alphabets " << endl;
    lowercaseAlphabets(ch);
 
    return 0;
}

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
