deletePos , what does it do ?

Hi;

which one is true and why

The function deletePos does the following (Array-Based List):
(a) shifts array elements one position to the left after the position
passed.

b) shifts array elements one position to the left overwriting the
element at the position passed.

 

deletePos is not a member of the C/C++ standard runtime library. You will need to refer to the documentation for whatever library you have that defines it.

 

this function is refer to the Array-Based List Class ;

so what does it do ;

my friend say B

but i am not sure about that .

becuse while shifting left , its allready make overwriting
