此部分提到的文章解释了编译器生成的一部分错误消息。 重要 Visual Studio 编译器和生成工具可报告多种类型的错误和警告。 发现错误或警告后,生成工具可做出有关代码意向的假设并尝试继续,因此,可能会同时报告更多问题。 如果工具做出错误假设,则后续错误或警告可能不适于你的项目。 纠正项目中的问题时,请始终先纠...
转义序列(字符),就是代码中不能或者很难用键盘输入的字符,比如,换行符,如果按enter, 编辑器会解析成下一行,不会在代码中保留下来,还有空格。 The space, tab and the newline are often referred to collectively as white space character, because they cause space to appear rather than making marks on th...
"If P points to the last member of array,then P+1 compares higher than P,even though P+1 points outside the array.Otherwise,pointer comparison is undefined". Comparing two pointers to distinct members of the samestructobject is allowed. Pointers to structure members declared later in the str...
C 指针的小小实验 更新: 空白指针,也被称为通用指针,是一种特殊类型的指针,可以指向任何数据类型的对象! 空白指针像普通指针一样被声明,使用void关键字作为指针的类型。 The void pointer, also known as the…

指向常量的引用(reference to const) 没有const reference,因为引用本身就是 const pointer (为了方便记忆可以想成)被 const 修饰(在 const 后面)的值不可改变,如下文使用例子中的 p2、p3。 使用 代码语言:javascript 代码运行次数:0 运行 AI代码解释
