It will be eaten, but as soon as you instanziate with non-integer/non-string you
get an error, see also C++:
#include <string>
using namespace std;
void show(int i)
{
}
void show(string s)
{
}
template<typename T> class test
{
public:
T data;
void p()
{
show(data);
}
};
test<int> mytest1;
test<int *> mytest2;
int main()
{
mytest1.p();
mytest2.p();
}
