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.

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

Each alphabet has it’s own(unique) ASCII value. So we initialize the character variable to A, and then using while loop we iterate until our character variable is equal to Z. C program checks with the characters underlying ASCII values. Inside while loop we increment the value of character variable by one for each iteration and also print the character present in it.

int main()
{
    char c;

    printf("Enter a character\n");
    scanf("%c", &c);

    return 0;
}

Output 1:
Enter a character
5
5 is not an alphabet

Output 2:
Enter a character
a
a is an alphabet

Output 3:
Enter a character
$
$ is not an alphabet

Output 4:
Enter a character
S
S is an alphabet

Output 5:
Enter a character
#
# is not an alphabet

Logic To Check Whether a Character is an Alphabet or Not

We accept the character from user as input. We check if the user entered character is greater than or equal to a and less than or equal to z OR the user entered character is greater than or equal to A and less than or equal to Z. If these conditions are met, then user entered character is an alphabet or else its not.

C Program To Print All ASCII Characters and Value

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

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

Note:
Total number of Character in ASCII is 256 (0 to 255).
0 to 31(total 32 character) is called as ASCII control characters.
32 to 127 character is called as ASCII printable characters.
128 to 255 is called as The extended ASCII codes.

C Program to Print ASCII Value of a Character

Lets write a C program to print/display ASCII value of a user entered character.

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

Data Type

char is character data type in C programming language. It stores single character information in it and has a corresponding integer value for the character, which is its ASCII value.

Source Code: C Program to Print ASCII Value of a Character

#include < stdio.h >

int main()
{
    char c;

    printf("Enter a character\n");
    scanf("%c", &c);

    printf("ASCII value of %c is %d\n", c, c);

    return 0;
}

Output 1:
Enter a character
A
ASCII value of A is 65

Output 2:
Enter a character
a
ASCII value of a is 97

Output 3:
Enter a character
1
ASCII value of 1 is 49

Output 4:
Enter a character
0
ASCII value of 0 is 48

Output 5:
Enter a character
$
ASCII value of $ is 36
