Pointing class property to another class with vectors
- by jmclem
I've got a simple class, and another class that has a property that points to the first class:
#include <iostream>
#include <vector>
using namespace std;
class first{
public:
int var1;
};
class second{
public:
first* classvar;
};
Then, i've got a void that's supposed to point "classvar" to the intended iteration of the class "first".
void fill(vector<second>& sec, vector<first>& fir){
sec[0].classvar = &fir[0];
}
Finally the main(). Create and fill a vector of class "first", create "second" vector, and run the fill function.
int main(){
vector<first> a(1);
a[0].var1 = 1000;
vector<second> b(1);
fill(b, a);
cout << b[0].classvar.var1 << '\n';
system("PAUSE");
return 0;
}
This gives me the following error:
1>c:\...\main.cpp(29) : error C2228: left of '.var1' must have class/struct/union
1> type is 'first *'
And I can't figure out why it reads the "classvar" as the whole vector instead of just the single instance. Should I do this
cout << b[0].classvar[0].var1 << '\n';
it reads perfectly.
Can anyone figure out the problem?
Thanks in advance
