What will happen when you attempt to compile and run the following code?
#include<vector> #include<iostream> #include<algorithm> using namespace std; void printer(int v) { cout<<v<<", "; } struct Sequence { int start; Sequence(int start):start (start){} int operator() () { return start++; //LINE I } }; int main() { vector<int> v1(5); generate_n(v1.begin(), 5, Sequence(5)); //LINE II for_each(v1.begin(), v1.end(), printer); return 0; }
- compilation error in LINE I
- the program outputs
5, 5, 5, 5, 5,
- compilation error in LINE II
- the program outputs
5, 6, 7, 8, 9,
- the program outputs
1, 2, 3, 4, 5,
- runtime error at LINE II
