Hi
My input string is as follows :-

ABC<-AFC:RFS<-DRP:KLE<-SJS:KLS

the required output string should be

ABC<-AFC<-DRP<-SJS

Means to strip down every string after :(colon)

The set should be of the form {{{A,B},{B,C},{C,D}},{{D,E},{E,F}}}

As suggested by you my current implementation look like

struct LetterPair
{
string First_element;
string second_element;
};

void createset()
{

You understood it correctly. Forget the boost thing for the time being. Also let me know i may use these structure one inside another.

With regard to this only let me know what code need to be written to have
format of this sort{{{A,B},{B,C},{C,D}},{{A,C},{C,E},{E,F},{F,P}}}
Kindly help
