Check Whether a Character is an Alphabet or not

Write a program to find whether a given character is an alphabet or not.


Method 1:

Using ASCII value of lowercase letters (a,b,c,...z) and uppercase letters (A,B,C,...Z), check whether the entered number falls in the ASCII Value range of the alphabet.
 
Implementation:

#include<stdio.h> #include<ctype.h> int main() { char c; printf("Enter a character:"); scanf("%c",&c); if((toascii(c)) > 65 && (toascii(c)) < 122) printf("%c is an alphabet",c); else printf("%c is not an alphabet",c); return 0; }

Output:

Enter a character:s
s is an alphabet
