C Program to Check Alphabet or Not

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C programming topics:

Operators in C Programming.

Basic Input and Output function in C Programming.
Basic C programming.
Conditional Statements in C programming.

String concepts in C Programming.

Program to Check Vowel or Not

In c programming, it is possible to take character input from the user and Check Alphabet or Not with the help of a very small amount of code. The C language has many types of header libraries which has supported function in them with the help of these files the programming is easy. The string manipulation is very easy in C programming. In today’s program, we will take a character in input and Check Alphabet or Not.

With the help of this program, we can Check Alphabet or Not.

Algorithm:-

1. Declaring the variables for the program.

2. Taking the input a character from the user.

3. Pass that character to check with condition for alphabet.

4. Printing the output.

5. End Program.

Program to Check Alphabet or Not:-

/* C Program that will Check the given input is a alphabetor not */
#include <stdio.h>
int main()
{
    
    //Declaring the variable for the for the program
    char c;
    
    //Taking the input character from the user
    printf("Enter a character: ");
    scanf("%c", &c);
    
    // if input is a charcter
    //printing the output for alphabet else not a alphabet
    if ((c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z'))
        printf("%c is an alphabet.", c);
    else
        printf("%c is not an alphabet.", c);
        
    return 0;
}

/* C Program that will Check the given input is a alphabetor not */

#include <stdio.h>

int main()

{

//Declaring the variable for the for the program

char c;

//Taking the input character from the user

printf("Enter a character: ");

scanf("%c", &c);

// if input is a charcter

//printing the output for alphabet else not a alphabet

if ((c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z'))

printf("%c is an alphabet.", c);

else

printf("%c is not an alphabet.", c);

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

c= it will hold the character value.

Input character from the user.

Program Logic Code.

Printing output Check Alphabet or Not.
