C ++在另一方法中使用方法的局部变量

Question

Does anyone know if there's a way to pass a variable that i have created inside of a method to another method . I am posting part of the code so that it is clearer what i need to do

int Point::trovaLato(Point *spigolo2, Point *sol_p, Point *pvet){
//code
//code
Point* lato=new Point(myvalue1,myvalue2,myvalue3);
return 0;
}

Now i want to use that variable 'lato' inside of

int Rettangolo::interseca(Point *sol_p, Point *pvet){
int ritlat, test;
test = punti[0]->trovaLato(punti[1], sol_p, pvet); //this works
if(test){
    test = punti[1]->trovaLato(punti[2], sol_p, pvet);//ok
    if(!test){
        ritlat = lato->intersecaLato(punti[1], punti[2]); //doesn't know what lato is ofcourse :(
//more code
}

Thanks a lot

Change the return type to Point , and return one:

Point Point::trovaLato(Point* spigolo2, Point* sol_p, Point* pvet){
  //code
  //code
  return Point(myvalue1, myvalue2, myvalue3);
}

If you really need to return an int , you can return an std::pair<int, Point> .
