Question 4

• What happens when you attempt to compile and run the following code? #include  #include  #include  #include  using namespace std; void myfunction(int i) { cout << " " << i; } struct sequence { int val,inc; sequence(int s, int i):val(s),inc(i){} int operator()(){ int r = val; val += inc; return r; } }; int main() { vector v1(10);fill(v1.begin(), v1.end(), sequence(1,1)); for_each(v1.begin(), v1.end(), myfunction); return 0; }Program outputs:
  A : 1 2 3 4 5 6 7 8 9 10 
  B : 10 
  C : 0 0 0 0 0 0 0 0 0 0
  D : compilation error
