review of quiz 2

1. array of 5 vectors (int) with empty elements.
     vector of 5 int elements each initialized to value zero.
2. requirement for aray/vector . memory allocated must be contiugous.. no space between elements.

 a + b == c + d  // all are r-values as nothing is modified..
1.assignment and cin >> x (input value
2.assignment statement
3.for (auto x: a)
the above 3 are l-values.
5. const in n;  can only initially constants can't give assign them later on.

constexpr int m = x; // not allowed. clear value must be known at compile time..
const int m = x ; // allowed

how to sort two vectors in parallel

vector<string> n1 = n;
vector<double = a

  sort(n.begin(), n.end())
   search for n[0] in n1
     use that index to find a1[i] in a2
