why should we use (ss>>n)
in if clause? we could use it directly as

is there anyway that we can store operator and make it functional
i have tried it by another approach but it is giving wrong answer
can u plz tell me the error?
"
vector<int> parseInts(string str)
{
stringstream s(str);
char ch;
int a;
while(s>>a||s>>ch)
{
g.push_back(a);
}
return g;
}
