[Exercise 7] ASCII Identification

Question

Please write a program that can identify a value's characteristic based on ASCII table. It must identify:

1. 0-9 is a digit
2. A-Z is a capital character
3. a-z is a small character
4. Besides those conditions, it shows '%c is unknown'.
    

Kindly use the given template to finish the task. Be advised that your outputs must be exactly the same as the shown outputs below.

Example(Template)

#include <stdio.h>
#include <stdlib.h>

/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char *argv[]) {
	char a;
	printf("Define:\n");
	scanf("%c",&a);
	
// Your condition starts from here
	
	return 0;
}

 

Input#1

Define:
6

Output#1

6 is a digit

 

Input#2

Define:
A

Output#2

A is a capital character

 

Input#3

Define:
f

Output#3

f is a small character

 

Input#4

Define:
/

Output#4

/ is unknown

 

Suggestion

It's time to use your favourite table: ASCII
