How many bits are there in a hexadecimal character or hexadecimal value such as "F"?

What kind of data can hold a signed integer with 32 bits of precision?

Generate the binary sequence for each decimal sequence:a.    0 through 7                                  b.    32 through 36

The following is a quantity represented in base-8 (octal). What is its representation in base-10 (decimal)? (The right-most digit is still the one's place, the next is the 8s place, ...) 772

A computer "nibble" consists of four "bits," each bit being either a 0 or a 1. If characters are represented using a code that uses a nibble for each character, how many different characters can be represented?

Print the binary representation for a real value between O and 1 that is input as a double, for as 0.72. Print "ERROR:" if the number cannot be adequately represented in binary with no more than 32 characters.
