C Program To Print All ASCII Characters and Value using For Loop

Lets write a C program to print/display all ASCII characters and its corresponding value using For loop.

Note: In C programming language, every alphabet, number and symbol has corresponding ASCII value(a integer number representing the character).

In C programming language, there are 256 ASCII Characters and ASCII Values. i.e., from 0 to 255.

C Program To Find Special Symbol or Not using Conditional Operator

Using Conditional / Ternary Operator determine, whether a character entered through the keyboard is a Special Symbol or not.

Note: ASCII values start from 0 to 255. So we have total of 266 ASCII values.

ASCII Code for Special Symbols
0 – 47
58 – 64
91 – 96
123 – 255

Ternary / Conditional Operator General Form

(expression_1) ? (expression_2) : (expression_3);

expression_1 is a comparison/conditional argument. expression_2 is executed/returned if expression_1 results in true, expression_3 gets executed/returned if expression_1 is false.

Ternary operator / Conditional Operator can be assumed to be shortened way of writing an if-else statement.

Expected Output for the Input

User Input:
Enter a Character
$

Output:
Character Entered Is a Special Symbol

Logic To Find Special Symbol or Not using Conditional Operator

Using Conditional Operator we write the condition, if user entered character is in between or equal to ASCII values 0 – 47 or 58 to 64 or 91 to 96 or greater than or equal to 123. We use Relational Operator and Logical Operators to accomplish the task.

If the condition in expression_1 is true, then whatever code is present in expression_2 gets executed. If condition is expression_1 is false then the code present in expression_3 gets executed.

Logic To Find Lowercase Alphabet or Not using Conditional Operator

Using Conditional Operator we write the condition, if user entered character is greater than or equal to ASCII Value 97(which corresponds to lowercase character a) and less than or equal to ASCII Value 122(which corresponds to lowercase character z).

If the condition is true, then user entered character is lower case English alphabet, if not, then its not a lowercase English alphabet.

C Program To Check For Alphabet, Number and Special Symbol

Any character is entered through the keyboard, write a C program to determine whether the character entered is a capital letter, a small case letter, a digit or a special symbol.

The following table shows the range of ASCII values for various characters:
Character A – Z : ASCII Value 65 – 90
Character a – z : ASCII Value 97 – 122
Character 0 – 9 : ASCII Value 48 – 57
Special Symbol : ASCII Value 0 – 47, 58 – 64, 91 – 96, 123 – 127

    scanf("%c", &ch);

Output 2:

i
i is an lowercase Alphabet

Output 3:

Output 4:
Enter a Character
$
$ is a Special Character

Logic To Check For Alphabet, Number and Special Symbol

We use &&(AND) operator check check for range. i.e., for number, we check from the range 48 to 57. To check if the user entered character lies in this range we use (ch >= 48 && ch <= 57). To check for multiple ranges we use ||(OR) operator. For example, for special symbol:


(ch >= 0 && ch <= 47) ||
(ch >= 58 && ch <= 64) ||
(ch >= 91 && ch <= 96) ||
(ch >= 123 && ch <= 127)

C Program To Print Lowercase Alphabet(a-z) using While loop

In this video tutorial we show you how to write C program to print all the lower case alphabets(a-z) using simple while loop.

C Program To Print Uppercase Alphabet(A-Z) using While loop

Note: In C programming language, every character variable holds an ASCII value rather than the character itself. You can check ASCII value of all the characters here: C Program To Print All ASCII Characters and Code

Note:
ASCII value range of lower case alphabets:
ASCII value of a is 97.
ASCII value of b is 98.
ASCII value of c is 99.
and so on till z ..
ASCII value of z is 122.

Source Code: C Program To Print Lowercase Alphabet(a-z) using While loop

#include < stdio.h >

int main()
{
    char ch = 'a';

    printf("Lowercase English Alphabets:\n");
    while(ch <= 'z')
    {
        printf("%c ", ch);
        ch++;
    }
    printf("\n");

    return 0;
}

Output:
Lowercase English 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

Logic To Print Lowercase Alphabet(a-z) using While loop

Each alphabet has it’s own(unique) ASCII value. We initialize the character variable ch to a. Alphabet a has a ASCII value of 97. 97 gets stored in ch. We iterate through the while loop until value of ch is less than or equal to z(i.e., upto ASCII value of z, which is 122). We print character value(%c) of the variable ch, which has the character and not the ASCII value. We keep incrementing the value of ch by 1 for each iteration of while loop.
