     I just started learning C++ and had to do some string parsing code for one of my classes. I couldn't figure out how to do it until later on, but I wrote these little functions to help those that learned in VB feel a little more at home in C++. At least when they deal with strings.

 
				

Pretty much just copy and paste these functions in your file, I would've made a header file but don't know how yet.

Note: Make sure you include the string.h or just #include

Function Prototypes:
string mid( int, int, string);
int instr( int, string, string );
string sleft( string, int );
string sright( string, int );

Function Definitions:
string mid( int posStart, int intLen, string strSearch )
{
return strSearch.substr(posStart, intLen);
}

int instr(int startPOS, string strSearch, string strFind)
{
//return strSearch.find(strFind);
return strSearch.find(strFind, startPOS);
}

string sleft(string strSearch, int intLen)
{
return strSearch.substr(0, intLen);
}

string sright(string strSearch, int intLen)
{
return strSearch.substr(strSearch.length() - intLen, intLen);
}
