Exam question

[clyde11]

Hi falks,
i got this question in a test, i'm almost positive
that all of the answers are incorrect:

in C++, the "inline" mechanism:

1. enable better run time prformance, while still
keep structuralism
2. is actually using the old C preprocessor
3. does not enable type checking while regular
calling to functiuons do
4. force the compiler to insert the function into
the code while helping improve running time.

i'm sure that 3 and 4 are incorrect, (inline is a recommendation to the compiler and of course it enable type checking)
i did not read anywhere that the preprocessor is involved in the inline mechanism process..

So, are you asking whether 1. is true or false?

I would also say that all the answers are incorrect.
The inline keyword can increase performance of some small functions, but can decrease performance on larger functions.
The maintaining structuralism part sounds right though.

I guess you just have to choose the answer that sounds the least wrong, just like I vote for the Prime Minister that would cause the least damage to Canada.
