i want to make class which has one string atributte. But if string has length more then 50 characters i dont want create object. What should i do?
{
if (paSlovo.length() <= DLZKA_SLOVA)
aSlovo = paSlovo;
else
delete this;
} ```
Instead of doing this trough the constructor you can do this with a function that will either provide you with the object if the criteria is met or you get a nullptr.
Make sure to correctly delete the object when done or make use of smart ptrs
//create object
bar* TryCreateMyObj(string const& paSlovo) const
{
//only create object if string is less than 50
if (paSlovo.length() <= DLZKA_SLOVA)
{
return new bar();
}
return nullptr
}
