return an empty vector c++ [duplicate]

The requirement is that I need to search a vector to see if it contains the value passed in as the parameter. If the value exists in the vector, I return the vector. Else, I return an empty vector. I am not sure how to return an empty vector in c++. hope you could help me. my mimic.h:

vector<Pair> map; 

my Pair.h:

 Pair(){ } ~Pair(){} string prefix; vector<string> sufix; 

Return vector function :

vector<string> Mimic::getSuffixList(string prefix){ int find=0; for(int i =0; i < map.size(); i++) { if(map[i].prefix == prefix) { find =1; return map[i].sufix; //sufix is a vector from a class called "Pair.h" } } if(find==0) { //return an empty vector. } }

Just

return vector<string>(); 

Or use list initialization (since C++11)

return {};
