Check Alphabet or Not in C
To check whether the input character is an alphabet or not alphabet in C programming, you have to ask to the user to enter a character and
start checking for alphabet with ASCII values. If character has ASCII values between 65 to 92 or between 97 to 122, then it will be an alphabet.
Otherwise, it will not be an alphabet. You can also check whether the character is in between a to z(alphabet) or A to Z(alphabet) or
not(not alphabet)
C Programming Code to Check Alphabet or Not
Following C program ask the user to enter a character to check whether it is an alphabet or not, then display the output on the screen:
/* C Program - Check Alphabet or Not */
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
char ch;
printf("Enter a character: ");
scanf("%c",&ch);
if((ch>='a'&& ch<='z') || (ch>='A' && ch<='Z'))
{
printf("%c is an alphabet",ch);
}
else
{
printf("%c is not an alphabet",ch);
}
getch();
}
When the above c program is compile and executed, it will produce the following result.
