The cancer-color proliferation also has created some quirky chromatic overlaps. Orange represents two cancers (kidney, leukemia). Green stands for three (liver, lymphoma gall bladder). Variations of purple signify six (pancreatic, testicular, leiomyosarcoma, Hodgkin lymphoma, stomach and esophageal).
If the container is empty, then begin() == end(); All standard iterator and container types behave the same in this regard: Â§23.2.1 [container.requirements.general] p6. begin() returns an iterator referring to the first element in the container.
double myA[100] = {}; array<double, 100> myB = {}; myA[0] is like a pointer, myB.begin() an iterator, if I do not make any mistake. So, what is exactly the difference between the pointer and the iterator here? They all give the access to elements. If I need the target of copy to be an array like myA which cannot give an iterator, is there a way to make the command copy work for it? Thanks in advance for replying.
