iterating over set c++ code example
Example 1: iterating a set c++
//Given set s
for(auto it: s){
cout << it << endl;
}
Example 2: iterate over a set in C++
//Method 1
// Iterate over all elements of set
// using range based for loop
for (auto& i : mySet)
{
cout << i << " , ";
}
//Method 2
// Iterate over all elements using for_each
// and lambda function
for_each(mySet.begin(), mySet.end(), [](const auto & str)
{
cout<<str<<", ";
});
//Method 3
set<string>::iterator it = mySet.begin();
// Iterate till the end of set
while (it != mySet.end())
{
// Print the element
cout << *it << ", ";
//Increment the iterator
it++;
}
