    Thanks, it works with the default constructor :)

      This worked fine until I added variables to the struct. The erro is as follows:

      main.cpp:46: error: no matching function for call to ‘VEdge::VEdge() ’
      VEdge.h:6: note: candidates are: VEdge::VEdge(in t, int, bool)
      VEdge.h:1: note: VEdge::VEdge(co nst VEdge&)

      I think it wants a constructor call of some sort...

        dynamic allocation

        Hi

        I am trying to create matrix of a struct I defined. It seems i cannot just sub in my struct name for float:

        Code:
        float **matrix;
int rows = 10, cols = 10;
matrix = new float* [rows];
for(int i = 0; i<rows; i++)
{
  matrix [i] = new float [cols];
}
        What can I do instead?

            creating an iterator

            Hi All

            I am trying to implement a hash table using separate chaining. I have declared a vector of list [vector< list<string> > myList]. I am now trying to create a makeEmpty( ) method. But I am having trouble wih creating an iterator for the list embedded in the vector.

            Cna anyone help me out?

            Thanks

              sorting vector continued.....

              I am trying to sort a vector containing objects of a class, using one of the instance variables as a key(int).

              I defined the operator overload as follows:

              Code:
              bool info::operator < (info &b){
	return getWeight() < b.getWeight();
	
}
              In the driver i have included <algorithm> and am using the sort method as follows:
              ...

                sorting vector

                Hi All

                I posted earlier.....
                I took advise on using the sort method in the STL under algorithms on a class that I created. Here is the operator overloading that i did but i cant seem to get it to sort at all. PLease help

                Code:
                bool info::operator < (info &b){
	if ( (*this).getWeight() < b.getWeight() )
	return true;
	else
	return false;
}

                  sorting a vector

                  Hi All
                  I was just wondering if its possible to use the sort method found in the STL algorithms class on a vector I declared as: " vector<myClass> myVector; "
                  where I want to sort according to one of the instance varaibles of myClass.

                  Thanks
