C or operator can this be done somehow?

Asked By Tony S Boudreau 30 points N/A Posted on - 08/01/2013

Hey guys,

Can c++ or operator be done? The code is:

if((a ||b)==0)return1;

return0;

boolCircle2::contains(Line2l){

 

if((p1.distanceFrom(l.p1)||p1.distanceFrom(l.p2))<=r){

 return1;

 }

 return0;

}

Is the coding in the second piece the problem? Any help would be awesome.

Hi Tony,
There seems to be problem in the first as well as second code.
In your code, you need to compare for Logical OR condition. Hence you need to write the expression as (a==0)||(b==0)
If you write it as ((a||b)==0), it implements that the logical OR of a & b is equal to 0.
Now, in the second code, you need to separately compare the value of 'r' with both, 'p1' and 'p2'. Hence the expression needs to be written as
If((p1.distanceFrom(1.p1)<=r)||(p1.distanceFrom(1.p2)<=r)), return 1;
