const vector<int>::iterator中,const是修饰的迭代器,也就是是个常迭代器,一旦初始化比如=a.begin(),再不能更改它的值,比如赋值=a.end()是不行的,递增递减操作等都不允许。 虽然类似指针,但指针是内置类型,所以编译器可以通过const的位置来判断是常指针还是指向常量的指针,而迭代器只是一个对象,所以编译器不...
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...
