Two very annoying mistakes

I am very good at doing silly mistakes in c++ syntax. Here are two of the most disturbing mistakes.

1. Forgetting to put ; after class declaration :

class mb


int a;



Error :  “expected unqualified-id at end of input”


2. Forgetting to leave a space after “>” in map declaration.

map<string,vector<double>> *a;

    Error : ‘>>’ should be ‘> >’ within a nested template argument list

    Correct syntax : map<string,vector<double> > *a;


The second one is more annoying . It made me google many a times 🙂
