C program to check character is alphabet or not

#include 
int main()
{
    char c; // character variables
    printf("Enter a character: "); // user enter character value
    scanf("%c", &c); // stpre value
    
        // check character or not
    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

Enter character *
* is not character

How program works ?

• In this program, 'a'  is used instead of  97 and 'z' is instead of  122.
• Similarly, "A" is used instead of 65 and "Z" is instead of 90. 

Happy coding
