I have the following code:
using namespace std;
map<int, vector<string> > map;
map<int, vector<string> >::iterator it;
and I get this error on the second line of code:
expected primary-expression before ‘int’.

2You probably need std:: before your declarations and/or you forgot to include the map include file. – Anon Mail Apr 10 '17 at 18:47

1But I'm using namespace std, so is that necessary? @AnonMail – Apr 10 '17 at 18:48

No. But you have not shown that in your code snippet! – Anon Mail Apr 10 '17 at 18:49

1@AnonMail sorry! updated. – Apr 10 '17 at 18:49

1Did you `#include – jxh Apr 10 '17 at 18:51

1@jxh yup! the problem is with the second line so I'd guess it's just the iterator that's messing up. – Apr 10 '17 at 18:52

4The second `map` is using your variable named `map`. – jxh Apr 10 '17 at 18:53

2jxh is correct - A hint would be that the syntax highlighter has colored your `map` variable light blue ;) – miradulo Apr 10 '17 at 18:56

The problem is certainly that your variable is the same name as its type (map). In the second line, the type specifier (<>) is applied onto 'map' the variable, and not onto the type 'map', which makes no sense.
Renaming it should solve the problem.

1You might want to reword this as an answer as opposed to a question, as it is almost surely the correct answer. – miradulo Apr 10 '17 at 18:56
