C++ (Cpp) FormatTimeStr Exemples

Exemple #1

Fichier : LiftingActivity.cpp Projet : msimms/Exert

std::string LiftingActivity::GetSocialNetworkStoppingPostStr() const
{
	std::string name = GetName();
	std::transform(name.begin(), name.end(), name.begin(), tolower);
	
	std::ostringstream str;
	std::string timeStr = FormatTimeStr(ElapsedTimeInSeconds());
	str << "Did " << name << " at " << timeStr << " (Tweet auto-generated by Exert App)!";
	return str.str();
}
