combining two overloads operators

[hanna88]

here's the problem.
i was given a test case v[0]=1.
in order to implement operator[],i need to get the access the value it is refering to which is 1.
i tried to write some code ignoring the = by assuming the compiler knows that = means assigning 1 to that position 0.and it turn out to be wrong.

so is it right if i'm assuming = as overload operator?
wouldn't it makes the test case to be

v.operator[](index).operator=(value);

but is that right?and how am i suppose to write the signature?

thanks in advance.

overload operators problem

here's the error i have in the test code:

error C2679: binary '=' : no operator found which takes a right-hand operand of type 'int' (or there is no acceptable conversion)

any hints to get the value that it is refering to?

you have something like this in your code:

myvalue& myvector::opera tor[] (const int index)...

and then compiler wants to assign int to myvalue
- you need to have
myvalue& myvalue::operat or=(int x)

Check this out for the [ ] overloading http://www.learncpp.com/cpp-tutorial...ript-operator/

I don't think you need to additionally overload the assignment operator for this particular case. Once you are accessing any particular element (by using the [ ] with the index) you can then assign to it with = as normal.

thanks for your reply.

im doing this using class.so should i make int x as a private member in order the function for operator[] to get the value x.

[hanna88]

myvalue& myvalue::operat or=(int x)

i got an error of

error C2440: 'return' : cannot convert from 'int' to 'Vector &'

where did i do wrong?

It depends on what _exactly_ code you tried to compile.
