Our task is to print the alphabets from A to Z using loops. There are various methods to print alphabets from (A to Z) or (a to z).
- Using ASCII values
- Using character variables.
In this article we will mainly focus on the following programs and their logic:
- Using for loop
- Using the while loop
- Using a do-while loop
Program to display alphabets using ASCII values
C++
// C++ Program to display alphabets using ASCII values#include <iostream>using namespace std;int main(){ int i; cout << "Alphabets from (A-Z) are:\n"; // ASCII value of A=65 and Z=90 for (i = 65; i <= 90; i++) { // Integer i with %c will be converted to character // before printing.%c will takes its equivalent // character value cout << (char)i << " "; } cout << "\nAlphabets from (a-z) are:\n"; // ASCII value of a=97 and z=122 for (i = 97; i <= 122; i++) { // Integer i with %c will be converted to character // before printing.%c will takes its equivalent // character value cout << (char)i << " "; } return 0;} |
C
// C Program to display alphabets using ASCII values#include <stdio.h>int main(){ int i; printf("Alphabets from (A-Z) are:\n"); // ASCII value of A=65 and Z=90 for (i = 65; i <= 90; i++) { // Integer i with %c will be converted to character // before printing.%c will takes its equivalent // character value printf("%c ", i); } printf("\nAlphabets from (a-z) are:\n"); // ASCII value of a=97 and z=122 for (i = 97; i <= 122; i++) { // Integer i with %c will be converted to character // before printing.%c will takes its equivalent // character value printf("%c ", i); } return 0;} |
Java
public class Main { public static void main(String[] args) { int i; System.out.println("Alphabets from (A-Z) are:"); // ASCII value of A=65 and Z=90 for (i = 65; i <= 90; i++) { // Integer i with %c will be converted to character // before printing.%c will takes its equivalent // character value System.out.print((char)i + " "); } System.out.println("\nAlphabets from (a-z) are:"); // ASCII value of a=97 and z=122 for (i = 97; i <= 122; i++) { // Integer i with %c will be converted to character // before printing.%c will takes its equivalent // character value System.out.print((char)i + " "); } }} |

Javascript
console.log("Alphabets from (A-Z) are:");// ASCII value of A=65 and Z=90for (let i = 65; i <= 90; i++) { // Convert the ASCII value to a character and print it console.log(String.fromCharCode(i) + " ");}console.log("\nAlphabets from (a-z) are:");// ASCII value of a=97 and z=122for (let i = 97; i <= 122; i++) { // Convert the ASCII value to a character and print it console.log(String.fromCharCode(i) + " ");} |
Output
Alphabets from (A-Z) are: 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 Alphabets from (a-z) are: 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 print (A to Z) and (a to z) using for loop
In the below program,
- For loop is used to print the alphabets from A to Z. A loop variable is taken to do this of type ‘char’.
- The loop variable ‘i’ is initialized with the first alphabet ‘A’ and incremented by 1 on every iteration.
- In the loop, the character ‘i’ is printed as the alphabet.
