How to filter data from tex file

geng07 (39)
Requirements in filtering the text file. OVERWHELMED TO ACCEPT SUGGESTIONS. THANKYOU :)

1. first my professor required me NOT to change the MAIN function(because he made it)

2. I have to make 3 getlogs() STRING FUNCTIONS:
a. string getlogs(); - accepts no paramters, SHOWS ALL THE CONTENTS OF TEXT FILE

b. string getLogs(const string & a); - accepts 1 parameter -SHOWS ONLY THE LINE WHICH CONTAINS THE SPECIFIED DATE FROM MAIN FUNCTION which is "2014-08-01"


c. string getLogs(const string & b, const string & c); - accepts 2 parameters, SHOWS ONLY THE LINES FROM THE DATE START to DATE END specified at THE MAIN FUNCTION which is date start-"2014-08-01";DateEnd = "2014-08-10";

3. all COUT should be in the MAIN FUNCTION

TEXTFILE CONTAINS:
2014-08-01 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-02 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-03 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-04 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-05 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-06 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-07 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-08 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-09 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-10 06:13:14,Name,4.5,CustomUnit,CustomType
2014-08-11 07:13:14,Name,4.5,CustomUnit,CustomType
2014-08-01 07:13:14,Name,4.5,CustomUnit,CustomType
2014-08-03 07:13:14,Name,4.5,CustomUnit,CustomType
2014-08-01 07:13:14,Name,4.5,CustomUnit,CustomType
2014-08-05 07:13:14,Name,4.5,CustomUnit,CustomType
2014-08-01 07:13:14,Name,4.5,CustomUnit,CustomType
2014-08-07 07:13:14,Name,4.5,CustomUnit,CustomType
2014-08-01 07:13:14,Name,4.5,CustomUnit,CustomType
2014-08-09 07:13:14,Name,4.5,CustomUnit,CustomType
2014-08-10 07:13:14,Name,4.5,CustomUnit,CustomType


REQUIRED OUTPUT SHOULD BE:

1.ALL CONTENTS
2. LINES WHICH CONTAINS THE DATE 2014-08-01
3. LINES FROM 2014-08-01 TO 2014-08-10

so far this is my codes, I appreciate your reccomendations and revisions :)

Please, do not double-post. The first thread should be enough: http://www.cplusplus.com/forum/unices/140803/
