need help with constructor

[hanna88]

hello there.
here's the problem.

//given 2 constructor

vector v1;
vector v2(parameter);

//member function 
n= intdotProduct(const Vector &x)

//in the test code it is given as
n=v1.dotProduct(v2);

i understand that x is refering to v2 in this case.
what about v1? how can i acces it? i tried using

this->somefunction to indicate this == v1 but come out with error

Error error C3867: 'Vector::getNumColumns': function call missing argument list; use '&Vector::getNumColumns' to create a pointer to member

any help would be much appreciated

The first constructor v1 needs parenthesis. i.e. v1();
Just call v1() with out any parameters.

I do not believe you have posted the code that the error relates to. It is saying that you have a member function of Vector, getNumColumns and that somewhere in the code there is the construct

Vector::getNumC olumns

i.e. the parentheses () are missing.
