| Q) Operator 
Overlaoded I have declared the "friend" 
function into my component class (e.g. CPU), such as the below:
 class computer;
 class CPU {
 friend computer& operator+= 
(const computer&);
  public: ...   
private: ... }
 But it gives me this error:
 d:\concordia\2nd semester\comp5421\assignment2\sourcecode_part2\cpu.h(13) 
: error C2805: binary 'operator +=' has too few parameters
 computer.cpp
 d:\concordia\2nd semester\comp5421\assignment2\sourcecode_part2\cpu.h(13) 
:
 error C2805: binary 'operator +=' has too few parameters
 Error executing 
cl.exe.
 A)If 
you declare/define the overloaded operator inside the class, then you need only 
one (Computer) parameter since the left-hand one will be the current object. Since 
you declared/defined the operator outside the class (similar to a free function), 
the operator needs two (Computer) parameters. That is why this error is returned.
 In short, you will need to have two parameters since the overloaded operator 
is not a member of the class.
