Question

I would like to know why i am unable to create a set.
I am getting the following error

Here is my codes.

Point.cpp My Point class

bool Point::operator<(const Point& p2)const {
return p21.length < p2.getScalarValue();
}

bool Point::operator>(const Point p2) {
bool result;
result = length > p2.getScalarValue();
return result;

}

and in my main.cpp

set<Point> s_p2;
Point tempp2;
s_p2.insert(tempp2);

After following your inputs, i have edited the codes and i have the following error

Point.cpp:56:46: error: passing ‘const Point’ as ‘this’ argument of ‘double Point::getScalarValue()’ discards qualifiers [-fpermissive]

Is this because i got two comparing statements ?

Answer 1

Managed to solve it. I need to make my get getScalarValue() const also.
as it only returns the value.

It complies and runs without error.
