Saraswathy  (10 years ago)

A.True

It is not sense to define functions more than once...The compiler cannot identify which function to execute if you define functions more than once... It ll throw an error...
But we can declare functions more than once, but all should be identical...

NIKHIL NAGRALE  (8 years ago)

A declaration only tells the compiler how to generate code to call the function. It is okay to tell the compiler the same thing several times(all declarations must be identical).

But a definition results in code to implement the function.With multiple definitions, the compiler will emit multiple copies of the function. Then the linker will see the function defined multiple times and not know which one you are trying to call. So multiple definitions are not allowed.
