Need help with a small program

#include <stdio.h>

main()
{
int i;
char c;

printf("Enter Char: ");
scanf("%c", &c);

printf("You entered %c\n", c);
printf("The ASCII value of %c is %d", c,c);

return 0;
}

Okay, that was simple enough, but I need something like this as my output.

printf("The ASCII value of %c is %d and it is a LETTER, DIGIT, or OTHERS", c,c);

I dont know how to setup the LETTER, DIGIT, or OTHERS parts. I know there are functions such as isdigit, but we cannot use them.

For example: if I enter A it will say that it is a LETTER or if I enter 5 it will say that it is a DIGIT and if I enter 'tab' then it will say OTHERS.

Can you guys help me out. I am svery stuck with this.

if ( c >= 'A' && c <= 'Z' )
if ( c >= '0' && c <= '9' )

Etc.

look at your ASCII table
pseudo code:

if( 47 < c < 58)
{
it's a DIGIT
}
else if( 64 < c < 91)
{
it's an uppercase LETTER
}
else if( 96 < c < 123)
{
it's a lowercase LETTER
}
else
{
it's some OTHER character
}
