. That is to say, the parameters can be defined as their basic types, which are representative of DWORD. 2) No code can be created in the header file, which only contains the definition information. If the header file must contain the code, it must be defined as a macro.3) struct should be defined according to their C prototype. 4) The GUID structure is defined in the windows. inc file.

be arranged vertically on the parent element .*/. Child{Display:Inline-block;vertical-align:Bottom;}The biggest difference between this example and the previous example is the addition of the Display:table-cell property, which, after adding this property, is like a cell in a table, and it is natural to use the Vertical-align property on the parent element to align the elements vertically. The vertical-bottom on the parent element is the alignment of the child element to the parent element as a

--------- Chapter 2 --------- 1. (P11) C ++ requires that, apart from being modified by typename, any symbol in the template is regarded as a value rather than a type. Eg. Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->Template Class myclass { Typename T: subtype * PTR; }; Here, typename indicates that subtype is a type defined in class T, so PTR is a po

. From the configuration above, we can see that we use the master node as the master node and as the data processing node. This is due to the consideration of three copies of our data and the limited number of machines. Copy the master configured masters and slaves files to the conf folder under the hadoop installation directory of slave1 and slave2 respectively: Go to the slave1 or slave2 node to check the content of the masters and slaves files: It is found that the copy is completel
