Vector elements

I have a number and a vector;
How can I check if a number is an element of a vector?
Thank you

Use the std::find algorithm.

Code:

---

for (int i=0; i<vec.size(); ++i)
{
  if (vec[i] == number)
  {
      cout << number << " is an element of vector." << endl;
      break;
  }
}

Is there any way that I could do it without a loop or vector size?

Not really. My method avoids calling size() and has no visible loop, but it's just hidden.

Use find() from header <algorithm> like CornedBee suggested. ;)
