Thread: Can you compile the following template function code?

Hello everyone,


Here is the code and related compile error information. I am using Visual Studio 2008. Not sure whether you can compile using your compiler? Why Visual Studio 2008 can not deduce template parameter type?

Code:

#include <iostream>

using namespace std;

template <class T> void f(int a) {g (a);}

void g(int a)
{
	cout << a << endl;
}

int main()
{
	f (100); // can not compile, error C2783: 'void f(int)' : could not deduce template argument for 'T'
	// f<int> (100) can compile
	return 0;
}

thanks in advance,
George
