How to read from stdin int using c++ skipping "," and "Space" till "\n"

Question

I want to read integers from STDIN, 1,2,3,4

vector<int> r;
cin >> is;
stringstream iss(is);
int n;
while(iss >> n)
{
    r.push_back(n);
}

but stops reading after "," is there a way other than splitting and directly read Integers only.

`int n; char c; while( iss >> n >> c ) { ... }` Either way, yes, you can split the line by separator. — user2296177, Jun 22 '16 at 06:18
@user2296177 `int n; char c; while( iss >> n >> c ) { ... }` will not read the last `int`. — Ahmed Akhtar, Jun 22 '16 at 06:29

Here you have to consume and skip the , after every digit as shown here:

vector<int> r;
cin >> is;
stringstream iss(is);
int n;
while(iss >> n)
{
    r.push_back(n);
    char c;
    iss >> c;
}

See running example here.
