Bfloat.RetrieveItem(a,found); // the errors are here
/*Bfloat.GetNextItem();*/ //
}
I am tryimg to call a function of a class template in the main
program. the instance Bfloat is calling the RetrieveItem method to
find a value in a float list.
ERROR:
templatedriver.cpp no matching function for call to
`SortedList<float>::RetrieveItem(ItemType&, bool&)'
candidates are: void SortedList<ItemType>::RetrieveItem(ItemType&,
bool&) const [with ItemType = float]
The function name is below.
template<class ItemType>
void SortedList<ItemType>::RetrieveItem(ItemType &a,bool &found) const
{
I had no errors with the InsertItem function. Can anyone help please?

Post a complete small program that exhibits the problem.

I did not find the declarartion of 'a' any where inside the code .I
guess the compiler did not either.Hence it has the right to complain.
