problem implementing BFS using string vector
 

Hi All,

The problem is that i have to read in a text file which is something like:

ASt BSt
BSt WSt
BSt YeSt
BSt KrSt
MSt KrSt

they are possible street intersections from ASt to MSt. I have to output the list of streets in order to reach MSt from ASt like:

ASt
BSt
KrSt
MSt

This is to be done using Breadth First Search.

The problem i am facing is that, i have stored the intersections in a string vector, but i am not able to compare two string vector elements.

Can anyone kindly help me out here. I already tried the == and compare function.
