Single Character Input‒getchar() function - Basic C Programs

Testing a character type.

/* Program to testing a character type */

#include<stdio.h>

main()

{

char ch; /* Local definition */

/* statements */

printf("Enter any Character/Digit........");

ch=getchar();

if(isalpha(ch)>0)

printf("It is a alphabet");

else if(isdigit(ch)>0)

printf("It is a digit");

else

printf("It is alphanumeric");

} /* main */

OUTPUT

1. Enter any Character/Digit......a

It is a alphabet

2. Enter any Character/Digit.......1

It is a digit

3. Enter any Character/Digit.......#

It is alphanumeric

EXPLANATION: In the above program the variable 'ch' declared as character type. The getchar() function reads only one character through the keyboard. The entered character is evaluated whether it is alphabet or digit or alphanumeric by using the respective functions. According to the entered character the output was produced.
