I have seen code which use vector,
vector<int>s;
s.push_back(11);
s.push_back(22);
s.push_back(33);
s.push_back(55);
for (vector<int>::iterator it = s.begin(); it!=s.end(); it++) {
cout << *it << endl;
}
It is same as
for (auto it = s.begin(); it != s.end(); it++) {
cout << *it << endl;
}
How safe is in this case the use of the auto keyword? And what about if type of vector is float
? string
?
