I need to write a program that inputs a character from the keyboard and tests it with each of the functions () in the character-handling library. The program should print the value returned by each function. Write a printf() statement to ask user for the following message.

Enter a character:

Test isdigit( ) function): Now, use isdigit() function to test whether user has entered a character or not as following:

if (isdigit(case) == 0)

{

printf("user has entered the character: %c ", );

}

The functions to test with are:

isblank(), islower(), iscntrl()

The display should look similar to this:

Enter a character: c

User has entered the character: c

Isblank(c) = 0

Islower(c) = 0

Iscntrl(c) = 0
