cout << numIntElement(inFile,j)<< endl;
cout << endl;
inFile.close();
inFile.open("int.dat");

inFile2.open("float.dat");

inFile2 >> z;
Bfloat.InsertItem(z);
}
Bfloat.ResetList();
for(int s=0;s<y;s++)
{

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.
