vector<string> cars = {"Volvo", "BMW", "Ford", "Mazda"}; cars.erase(cars.begin() + 1); for (string car : cars) { cout << car << "\n"; }Try it Yourself » Definition and UsageThe erase() function removes an element or a range of elements from a vector. The elements ...
vector中的remove的作用是将等于value的元素放到vector的尾部,但并不减少vector的size vector中erase的作用是删除掉某个位置position或一段区域(begin, end)中的元素,减少其size list容器中的remove 成员函数,原型是void remove (const value_type& val); 他的作用是删除list中值与val相同的节点,释放该节点的资源。
// An empty specification list says that the function does not throw any exception // 析构函数不抛出任何异常 virtual ~custom_exception() throw() { } }; // 这个类将作为Vector中元素的类型 class Student { public: Student(const string name = "Andrew", constint age = 7) : name(name), ...
对于vector一般不要用erase(),因为很多情况下他要和<algorithm>中的remove()一块用！erase（）的使用会使迭代器失效如果删除的不是最后面的元素的话。你的程序中if(*iter%2==0) ivec.erase(iter); 可以换成：（记着加头文件<algorithm>）if (*iter%2 == 0)ivec.erase(remove(ivec.begin(...
A random access iterator pointing to the new location of the element that followed the last element erased by the function call, which is the vector end if the operation erased the last element in the sequence. 删除值为3的元素,按说it = vec.erase(it); 是正确的,但是我实验...

Assertion given for erase() vector function Aug 19, 2010 at 2:35pm jaeger138 (39) This piece of code is meant to erase an item of choice from a vector but for some reason every time it runs I get the assertion: Expression:vector iterator + offset out of range Not sure precisely ...
