Question

What do i have to do to this code to make it compile, it’s braking around this line:

auto val = what.getObject();

#include<iostream>
using namespace std;

class CUP{
    public:
        void whatsHappening(){}
};

class MUG{
    public:
        void whatsHappening(){}
};

class CupThrower{
    public:
        CUP cp;
        CUP getObject(){ return cp;}
};

class MugThrower{
    public:
        MUG mg;
        MUG getObject(){return mg;}
};

template <typename T> void whatsHappening(T what){

    auto val = what.getObject(); //DOES NOT COMPILE
    val.whatsHappening();
}

int main(){
    CupThrower ct;
    MugThrower mt;
    whatsHappening(ct);
    whatsHappening(mt);
    return 0;
}

i am using VS2008 to compile.

Auto isn’t supported in VS2008. Use VS2010 and later versions, or another compiler supporting this feature.
