vector<SomeClass>::resize

[pauldepstein]

Suppose a vector taking elements in SomeClass is resized from length 5
to length 8 using the resize method. SomeClass is a class which takes
a variety of constructors SomeClass contains a constructor
SomeClass() another constructor, SomeClass(int) etc.

What then would the values be of the new values being appended via the
resize method. Would they be equal to SomeClass() ?

In other words, would they be initialized with the empty parameter
list?

Thank you,

yes. all sequence containers define resize as

void resize(size_type sz, T c=T() )

yes. all sequence containers define resize as

void resize(size_type sz, T c=T() )

in that case the copy constructor is used . I mean every new object is
copied from c .
