C++ Test questions..Any ideas?

[maverick_pol]

I have 2 question from a C++ test, that I am not sure of:quote:

1. Which stream status bit indicates EOF?

a. OxOO
b. OxO1
c. OxO2
d. OxO3
e. OxO4
f. OxO5
g. OxO6
h. None of the above

2. Which of the following conditions should satisfy the basic type casting in class ?


a. It must be a class member
b. It must not specify a return type.
c. It must have arguments
d. All
e. None

Any ideas and explanation appreciated.

1. Which stream status bit indicates EOF?

a. OxOO
b. OxO1
c. OxO2
d. OxO3
e. OxO4
f. OxO5
g. OxO6
h. None of the above

enum io_state   {
        goodbit  = 0x00,    // no bit set: all is ok
        eofbit   = 0x01,    // at end of file
        failbit  = 0x02,    // last I/O operation failed
        badbit   = 0x04,    // invalid operation attempted
        hardfail = 0x80     // unrecoverable error
        };

enum io_state   {
        goodbit  = 0x00,    // no bit set: all is ok
        eofbit   = 0x01,    // at end of file
        failbit  = 0x02,    // last I/O operation failed
        badbit   = 0x04,    // invalid operation attempted
        hardfail = 0x80     // unrecoverable error
        };

and what about this one:

2. Which of the following conditions should satisfy the basic type casting in class ?

a. It must be a class member
b. It must not specify a return type.
c. It must have arguments
d. All
e. None

Thank for the the post above.

I assume the questions are originally in Polish. If so, could you quote the original question? The translation doesn't seem precise (for example what is "it"? The class? The cast? Casting to what?)

[maverick_pol]

These questions were copied/pasted from Odesk.com C++ test. Still this does not prove that there are no mistakes.
I think your assumptions about

... the questions are originally in Polish.

are not true, but there is always a possibility that you may be right.

Here is the answer for the second question(if we are talking about class cast operator):
