Edit: One of the sites I've looked at that leads me to believe my syntax is correct: http://www.cprogramming.com/tutorial/templates.html
I've explored around Google a good deal before coming here to ask this question, since near as I can tell I've written things properly according to the examples that I have seen. For a homework assignment, writing a template class that does some extremely basic math stuff (sum, average, minimum, maximum, etc). When I attempt to compile to try and start debugging, I end up with the following error.
error: expected unqualified-id before '<' token
Following is somewhat snipped code, prototypes and a few lines before the chunk that errors. The code throws the error on the second line (the ones that start with lessthansymbol myType greaterthansymbol). I'm sure once I get past this I'll have plenty more things to debug with the program, but this is completely holding me up at the moment.
template <class myType>
class simpleSet
{
public:
static const int VALUE_MAX = 1000;
static const int CNT_MIN = 10;
static const int CNT_MAX = 500;
simpleSet();
simpleSet(int, myType[]);
~simpleSet();
void gnomeSort();
void generateNewSet(int);
myType minimum() const;
myType maximum() const;
myType median() const;
myType sum() const;
myType average() const;
myType linearRegression(const simpleSet&) const;
myType getDatum(int) const;
void setDatum(int, myType);
int getLength() const;
void printSet() const;
int readCount();
private:
int setLength;
myType *mySet;
};
template <class myType>
void simpleSet<myType>::generateNewSet(int size)
{
setLength = size;
for (int i = 0; i < setLength; i++)
{
mySet[i] = static_cast<myType>((myType(rand()%VALUE_MAX)));
if (mySet[i] < 1 || mySet[i] > VALUE_MAX)
{
i--;
continue;
}
}
}
template <class myType>
<myType> simpleSet<myType>::maximum() const
{
myType worker = mySet[0];
for (int i = 0; i < setSize; i++)
{
if (worker < mySet[i]) worker = mySet[i];
}
return worker;
}
template <class myType>
<myType> simpleSet<myType>::minimum() const
{
myType worker = mySet[0];
for (int i = 0; i < setSize; i++)
{
if (worker > mySet[i]) worker = mySet[i];
}
return worker;
}
template <class myType>
<myType> simpleSet<myType>::median() const
{
if (setSize == 1) return mySet[0];
else if ((setSize % 2) == 1) return (mySet[(setSize/2)]);
else return (average((mySet[setSize/2] + mySet[(setSize/2)-1])));
}
template <class myType>
<myType> simpleSet<myType>::sum() const
{
myType temp;
for (i = 0; i < setSize; i++) temp = temp + mySet[i];
return temp;
}
template <class myType>
<myType> simpleSet<myType>::average() const
{
return (mySet.sum()/setSize);
}
template <class myType>
<myType> simpleSet<myType>::getDatum(int item) const
{
return(myset[item]);
}
You don't need <myType>
on all the return values. Just myType
(no angle brackets) Also don't need to include <myType>
in the class scope (ie myType simpleSet::median()
.
