Create the class Vector with three members x, y, z - private integers.
Implement in the class three constructors:
default constructor that sets to 0 the class members.
constructor with parameters, the parameters are the vector coordinates
copy constructor.
Implement the methods:
double length() - return the length of the vector;
void setX(int), void setY(int), void setZ(int) - methods that change the corresponding values of the vector;
int getX(), int getY() int getZ() - methods that return the corresponding coordinates of the vector.
void Out() - print the coordinates of the vector, separated by a space, then print a new line symbol.
Submit the class only.
