C++ query

  
    int listsize, count;
    cout<<"Define size of list: ";
    cin>>listsize;
    cout<<endl;
    int list[listsize];

Are there any problems with this? It works fine but I just want to make sure I'm not committing a faux pas.


cin>>listsize;

Never ever EVER do that.¹

Do this:

#include <sstream>
#include <string>
and

string line;
getline( cin, line );
stringstream( line ) >> list[count];

Now that's proper input!²
