Understanding problem with task: "Testing bits of integer"

[quarkse]

Hey, I am trying to understand the task, but I do not really get it.
I shall write a program that prompts for an integer number and stores it into a variable of data type int. The program should test all bits of this variable by using C langauge bit operators and print the result. (1 = bit set, 0 = bit not set) to stdout. The program must work correctly for any length of the int data type(by using sizeof()).

Tbh I do not really understand the meaning of it. Does it mean I should do a decimal-to-binary conversion by using C language bit operators?

What means "test all bits of the read integer variable"? I means "test" in this case? What should you test?

I do not want you to solve this problem, but maybe you know what this task could mean.

For example, if you typed in the number 5, you would expect

bit 2 is set
bit 1 is clear
bit 0 is set

You test the least significant bit with
if ( (value & 1) == 1 )

You can shift bits around with say
value <<= 1
or
value >>= 1

You get the number of bits by doing say
sizeof(value) * CHAR_BIT
CHAR_BIT is defined in the header file limits.h.
