栈(stack)用于保存函数中的形参、返回地址、局部变量以及函数运行状态等数据。栈区的数据由编译器自动分配、自动释放,无需程序员去管理和操心。当我们调用一个函数时,被称为函数入栈,指的就是为这个函数在栈区中分配内存。 堆(heap)堆内存由程序员手动分配、手动释放,如果不释放,只有当程序运行结束后,操作系统才会...

In Visual Studio 2015, you must now add whitespace between the two strings. For example, the following code must be changed: C++ Copy char * str = "abc""def"; To fix this issue, add a space in between the two strings: C++ Copy char * str = "abc" "def"; Placement new ...
