在C++中,可以使用指针来访问vector中的元素。以下是一个示例,展示了如何返回指向vector元素的指针: 代码语言:cpp 复制 #include<iostream>#include<vector>int*getElementPointer(std::vector<int>&vec,intindex){return&vec[index];}intmain(){std::vector<int>vec={1,2,3,4,5};int*ptr=getElementPointer(...
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...
