若要删除std::vector中的element,正规的方式该用find() generic algorithm,若find()找到了,会传回该iterator,若找不到,将传回vector.end()。这种写法远比用for loop干净很多。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com 3 4 Filename : VectorFindAndErase.cpp 5 Compiler : Visual C++ 8.0...

这两个方法是与std::vector::begin和std::vector::end相对应的,从字面就能看出来,多了一个’c’,顾名思义就是const的意思。 所以: std::vector::cbegin:Returns a const_iterator pointing to the first element in the container. std::vector::cend:Returns a const_iterator pointing to the past-the-...
