How to Find a Substring in a Particular String in a Set

问题

How do you find the substring within a string in a set? For example, if I enter "Ville," then Louisville, Gainesville, and Muellerville are found? I have tried the following code

for(string const& search : cities)
{
if(find(search.begin(), search.end(), str) != std::string::npos)
{
string y = search;
employees.emplace_back(y);

,but I cannot figure out what is wrong with my syntax. This code is used in the following project (Project Code)

回答1:

You are likely looking for

if (search.find(str) != std::string::npos)

The std::find call you have shouldn't compile.
