I need help filling in this code, I am creating a class in C++ to parse through a string and each method needs to be filled in. The parameters and directions for each method are commented out above the start of the method. Help would be greatly appreciated!

#include #include #include #include "../327_proj3_test/includes/StringParserClass.h" #include "../327_proj3_test/includes/constants.h"

namespace KP_StringParserClass{

class StringParserClass {

//dont forget to initialize member variables StringParserClass(void){

}

//call cleanup to release any allocated memory virtual ~StringParserClass(void){

}

//these are the start tag and the end tags that we want to find, //presumably the data of interest is between them, please make a //COPY of what pStartTag and pEndTag point to. In other words //DO NOT SET pStartTag = pStart //returns: //SUCCESS //ERROR_TAGS_NULL if either pStart or pEnd is null int setTags(const char *pStart, const char *pEnd){

}

//First clears myVector //going to search thru pDataToSearchThru, looking for info bracketed by //pStartTag and pEndTag, will add that info only to myVector //returns //SUCCESS finished searching for data between tags, results in myVector (0 or more entries) //ERROR_TAGS_NULL if either pStart or pEnd is null //ERROR_DATA_NULL pDataToSearchThru is null int getDataBetweenTags(char *pDataToSearchThru, std::vector &myVector){

}

void cleanup(){

}

//Searches a string starting at pStart for pTagToLookFor //returns: //SUCCESS found pTagToLookFor, pStart points to beginning of tag and pEnd points to end of tag //FAIL did not find pTagToLookFor and pEnd points to 0 //ERROR_TAGS_NULL if either pStart or pEnd is null int findTag(char *pTagToLookFor, char *&pStart, char *&pEnd){

}

char *pStartTag; char *pEndTag; bool areTagsSet; } }

Header files are given below that I have implemented into the .cpp file above. There is also a FileIO class I have written but I don't think that this stringparser class needs to implement any of that.
