Prevent duplicates in a vector.sort(),Unique()

[conor0callaghan]

I have a bit of a problem, if anyone can help I would be very gratefull!

I have a vector full of strings, this vector expands each time it receives a string, but I dont want it to take in duplicates, It is very important that the vector keeps the strings in the same order that they were received first.

vec_Files["this.h","that.h","These.h","those.h","that.h","those.h"]
i want
vec_Files["this.h","that.h","These.h","those.h"]

I'm thinking of using the sort() function and unique() but they wont keep the order!

Thanks

The answer to this is to have a second list of pointers that point into the vector array. Sort the pointer array and base things off of that.

P.S. You could use qsort and bsearch for this.
