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...
std::vector::cbegin和std::vector::cend 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 ...

这是一篇 C 语言与 C++面试知识点总结的文章。 const 作用 修饰变量,说明该变量不可以被改变; 修饰指针,分为指向常量的指针(pointer to const)和自身是常量的指针(常量指针,const pointer); 修饰引用,指向常量的引用(reference to const),用于形参类型,即避免了拷贝,又避免了函数对值的修改; ...
vector or a string while a containing table is being updated which simplifies parsing of external formats. It is also possible to build nested buffers in-line - at first this may sound excessive but it is useful when wrapping a union of buffers in a network interface and it ensures proper ...
