void getAllDataByPointer(string *pname,double *platitude, double *plongitude);
void getAllDataByReference(string &pname,double &platitude, double &plongitude);
double calculateDistance(const CWaypoint& wp);
void print(int format);
bool less(const CWaypoint& wp_right);
CWaypoint add(const CWaypoint& wp_right);

These are the functions I am using. I have the values as output but how to call the latitude values of two different cities so that I can use the following formula

    distance = ERADIUS * (acos(sin(latitude_1)*sin(latitude_2) + cos(latitude_1) * cos(latitude_2)*cos(longitude_2 - longitude_1)));

I have a hook system setup... which is working on localhost... I put it live and get an error saying "Warning: Call-time pass-by-reference has been deprecated". Now, apparently the work around is to remove all "&" from your function calls, ie foo(&$me) to foo($me) and then in foo's function… >>> More

Can you pass by reference with "R" ? for example, in the following code: setClass("MyClass", representation( name="character" )) instance1 <-new("MyClass",name="Hello1") instance2 <-new("MyClass",name="Hello2") array = c(instance1,instance2) instance1 array instance1@name="World… >>> More

Hi everybody. Consider something like: struct Parameter { int a; Parameter(){a = 0} void setA(int newA){a = newA;} }; struct MyClass { void changeParameter(Parameter &p){ p.setA(-1);} }; Well, let's fast forward, and imagine I already wrapped those classes, exposing everything… >>> More
Simulating pass by reference for an array in Java

as seen on Stack Overflow - Search for 'Stack Overflow'
I was wondering, in java, is it possible to in anyway, simulate pass by reference for an array? Yes, I know the language doesn't support it, but is there anyway I can do it. Say, for example, I want to create a method that reverses the order of all the elements in an array. (I know that this code… >>> More
