Behind a lot of similar content,,,,


The file is composed of many of the same paragraph format,
Required functionality is: will the same ENCLOSED_AREA under the DESCRIPTION of this a numerical summation,

I now read through a CFile object pBuff, then how to judge and remove all ENCLOSED_AREA under the same DESCRIPTION?
Thank you all for the

CodePudding user response:

Should have no difficulty, this is the analytical data, you define a data structure, such as
Typedef struct _tagXXXXINFO
{
TCHAR szDescription [XXX];
TCHAR szName [XXX];
.
} XXXINFO;
Parsing the file content, parsing a dynamically allocated a pointer to the object of type, the data properly filled, then the pointer into the list (or use the STL containers such as map, is mainly defined what is the key, add the time before you need to check about whether there is accord with the condition of item, meaning that the same ENCLOSED_AREA) under the same DESCRIPTION, and so on,
