i.e. iostream for std: :cout, vector for std : :vector, and algorithm for std : :find. Vector ‘vec’ is initialized to its elements and the element to be searched is given in the variable ‘search_element’. Iteratot ‘it’ is used to store the result of the find() function...
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...
