Cleaning strings in a c++ function, is it necessary?

Question

C++ / C#

I asked myself this question, is it necessary to clear the lines inside the function, does this make sense?
for example:

std::string test(std::string object)
{
std::string new_object = object;
std::string request = request_server(SOME_HOST, new_object);

new_object.clear();

return request;
}

If you read the tutorial, you can find out what happens to local variables when a function exits.
And if you write in C ++ - the textbook is definitely worth reading.
