Set.insert return value

#1

In this question, is the output 0 because by default ret.second i.e., the initialized value of bool is 0?

hello @niveditha_palli

pls share the question with me.

It’s question 13 : What will be the output of following C++ code? #include <bits/stdc++.h> using namespace std; int main() { sets; pair<set::iterator, bool> ret; s.insert(1); s.insert(5); s.insert(10); s.insert(3); ret = s.insert(10); cout<<ret.second<<endl; return 0; }

@niveditha_palli

insert returns a pair.
here is the detail->
a pair with its member pair::first set to an iterator pointing to either the newly inserted element or to the equivalent element already in the set. The pair::second element in the pair is set to true if a new element was inserted or false if an equivalent element already existed.

output is 0 because 10 was already there in the set
