Чтобы преобразовать строку в вектор токенов (потокобезопасный):
std::vector<std::string> inline StringSplit(const std::string &source, const char *delimiter = " ", bool keepEmpty = false)
{
std::vector<std::string> results;
size_t prev = 0;
size_t next = 0;
while ((next = source.find_first_of(delimiter, prev)) != std::string::npos)
{
if (keepEmpty || (next - prev != 0))
{
results.push_back(source.substr(prev, next - prev));
}
prev = next + 1;
}
if (prev < source.size())
{
results.push_back(source.substr(prev));
}
return results;
}
