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 #, or any single character, by using std::istream::ignore

std::istringstream sstr("1024 # 768");

int main()
{
   int a, b;
   sstr >> a; 
   sstr.ignore(256,'#');   // ignore until hash character
   sstr >> b;
   std::cout << "a: " << a << " b: " << b << std::endl;
}
