Thread: Why my template function does not getting called?

  1. #1

    Why my template function does not getting called?

    Following code always invoke non-template function. Why?

    template<typename T>
    T GetData(T objT)
    	return objT ;
    int GetData(int nData)
    	return nData ;
    Void UseTemplate()
    	float f = 10;
    	int nData = GetData(10) ; //this does not invoke template function. why?
    	nData = GetData(f) ;

    This is called Overload Resolution of Function Template calls.

    Compiler identifies the best match for you and call that function.

    In that way your template function does not getting called for integer data type.

    For float, it will use the template function.
