C++ comparing bunch of values with a given one

Question

I need to compare one given value with a retrieved values. I do this several times in the code. I am not satisfied with how it looks and I am seeking for a some sort of an util

Answer 1

i like the collections approach, maybe use a hash_set instead of a vector. store the values in a property file and have a method to populat the hash_set from the file, and another one to return a boolean if the value is in the hash_set. then you can get down to one 2 lines in the main code.
