Topic request is to achieve the following six functions, I can now write the code to achieve the first two functions, after the communication with the teacher, I the problems existing in the code should be failed to put the file information stored in a structure, I use strncpy_s functions in your code, want to copy the message to the structure of the items, but the realization of the function of the back, has been stuck here for a long time, still no progress, can see where is wrong?
(1) to list the log file reading and writing;
(2) calculating the log file types the GET request proportion;
(3) to access a status code analysis and statistics, calculating the ratio of all access status code;
(4) analysis of IP address access to the most customers, and statistics the visits;
(5) analysis of commonly used password and statistical password usage;
(6) the user to enter the time, to find the time to visit record and output to a file
