How can we make a template accept only basic data types.
template <typename T>
void GetMaxValue( T& x )
{
//... Finds max Value
}
In the above function GetMaxValue
we are able to pass any value without any an error.
But the std Function std::numeric_limits<T>::max()
has handled it. For example:
auto max = std::numeric_limits< std::map<int,int> >::max();
will Give an error error C2440: '<function-style-cast>' : cannot convert from 'int' to 'std::map<_Kty,_Ty>'
