c++ - Skipping expected characters like scanf() with cin

Question

How to achieve scanf("%d # %d",&a,&b);sort of effect with cin in C++ ?

Answer 1

You can skip the # by extracting it into a character:

std::istringstream iss("10 # 20");

int main()
{
   int a, b; char hash;
   iss >> a >> hash >> b;

   assert(a == 10 && b == 20);
}
