Value and size of an uninitialized std::string variable in c++

Question

If a string is defined like this

std::string name;

What will be the value of the uninitialized string \"name\" and what size it would be?

Answer 1

value is null , and size is 0 But you can directly chk if the string is empty or not by empty()

Just in case you want to check that in your application , Do this

std::string name // Construct an empty string  
if(name.empty()) { // Check if its empty
  name="something";
}
