Q: 6
What happens when you attempt to compile and run the following code?
#include
#include
using namespace std;
template
class A {
T_v;
public:
A() {}
A(T v): _v(v){}
T getV() { return _v; }
void add(T & a) { _v+=a; }
void add(string & a) {
_v.insert(0, a);
}
};
int main()
{
Aa("Hello");
string s(" world!");
a.add(s);
cout << a.getV() <<endl;
return 0;
}
