Also if I say have a vector of ints and just push back 0; to make a space can I then change the value in the future via vec.back()=1; or even dereferenceing an iterator and simply changing the dereferenced value? If I have a vector that is a class member and use an iterator ...
I am trying to write my own version of STL vector<T> class. I have troubles on the end() function; for example: 12345 MyVec<int> vec; ... //put some value in vec MyVec<int>:: iterator itr = vec.end(); itr--; the vec.end() should return a NULL value, but the itr--...

11 12 structPoint {doubleX;doubleY; };classCircle {private: Point Centre;doubleRadius;// rest of class omitted for brevity} With the thethis->, another reason I prefer to put Arg, so I don't have to havethis->everywhere. What makes the initializer list the preferred option?
This JEE unit's scores resemble those of coordinate geometry in some ways. Along with some mathematics, it also contains complex numbers. You can easily earn high grades for this chapter if you correctly comprehend some difficult vector and 3D geometry concepts. Try to grasp the fundamentals, ...
From the class 12 syllabus, 17 questions were asked while 13 questions were prepared from the class 11 syllabus. There were 12 questions from physical chemistry, 10 from organic chemistry, and 8 from inorganic chemistry. Out of these, 16 questions were on a moderate level, 11 questions quite...

(hint: observe that the matrix in question produces a vector perpendicular to x x .) therefore,the angle θ θ that the particle makes with the horizontal axis increases at one radian per unit time, so θ = t θ = t . from the geometrical picture, this means that the coordinates of ...
To overcome the limited expressive power of a single state vector representing com- plex, 3D scenes, more recent approaches have modelled scene memories as either a buffer of observed egocentric features [13, 14], 2D metric grids [1, 3, 5, 7], topological maps [24, 31] or full-scale ...
