[Frustration] Pointer Class Object Vectors

Okay, so first thing's first. The program will not compile due to lines 39-45.
If I were to change those pointers into regular objects, it will not change the values of my class object. So what is the right way to do this?
I want the user to be able to input the # of employers/programmers into the system. But I cannot do that with an array of classes because when declaring an array; the array size must be constant.

I'd use a reference to a vector instead of a pointer, but it is possible either way. With a pointer, to access the data you'll need syntax like:
(*employer)[i].realname

[MienTommy]

How would you use a reference to a vector?

Okay, and now I changed lines 39-45 to (*employer)[i], but now another compile error appears on line 27.

Error	1	error C2664: 'enterInformation' : cannot convert parameter 1 from
 'std::vector<_Ty> *' to 'std::vector<_Ty>'	c:\documents\visual studio

Your prototype needs to say the function takes a pointer to a vector, as your implementation does.

[J4ke]

Instead of *employer[i]->realname, make sure you are using employer[i]->realname this is because in the first piece of code you are dereferencing employer, and then dereferencing it again by using the -> operator. Remember, the -> operator takes the instance at the location of the pointer and finds the instance of it.

Edit: If you still get the same error you that you got in your last post, replace the -> with a dot.

Never mind, I thought about this for a few seconds and realized that this won't work.

better go ahead with static vectors instead of pass by reference!!!

when you use pointers in lines 39-45, you have to change all of your codes to use pointers
if you dont change them, you will get this errors
or you can convert variables to pointers
