std::map<std::string, std::string> stdMap = ...;
for (const std::pair<std::string, std::string> &e : stdMap)
doSomething(e.first, e.second);
for (const auto &e : stdMap)
doSomething(e.first, e.second);
The second loop is at least two orders of magnitude faster (doSomething() is
an out-of-line no-op).
Thanks,
Marc
