nodes in vectors

well seems like the number of problems i encounter never ends...

I have a vector with nodes (each node contains several items, say x,y,z). I am trying to read the values in each node, and I can't succeed (it compiles and links, but the output is 1 all the time). Here's what I did:

Code:

class block_class
{
public:
  block_class();
  block_class( etc...);
  int get_x() { return x;};
  int get_y() { return y;};
  int get_z() { return z;};
  etc...
private:
  int x,y,z;
}

Code:

// the driver function
vector<block_class> list;
block_class A;
...fill in block A (assign values to x,y,z) and do list.push_back(A)...
...fill in block A again with different values and do list.push_back(A)...
...do the above for a few times until the list vector is populated with block_classes...

and now I want to do something like list[0].get_x or list.at[0].get_x and I can't. So what I did was:

Code:

block_class X = list[0];
cout<<X.get_x;

which keeps returning "1"

Please advise.

>> cout<<X.get_x;
I assume you mean cout<<X.get_x();.

>> I want to do something like list[0].get_x or list.at[0].get_x and I can't.
Why can't you? It should work (with the parentheses of course) to do list[0].get_x() or list.at(0).get_x().

With such a simple issue, you should be able to make a complete program with that class and a main that has your vector, some population code, and the incorrect output. Try making such a program and if you don't find the problem while doing that, then you can post it so we can see and/or run it ourselves.

sir, i really appreciate your help. my friend just realized that the prob was caused by shallow copying in another func. thank you for your lightning responses tho!!
