What happens when you attempt to compile and run the following code?

#include

using namespace std;

templatestruct Out {

ostream & out;

Out(ostream & o): out(o){}

void operator() (const T & val ) { out<

struct Add {

int operator()(int & a, int & b) {

return a+b;

}

};

int main() {

int t[]={1,2,3,4,5,6,7,8,9,10};

vector v1(t, t+10);

vector v2(10);

transform(v1.begin(), v1.end(), v2.begin(), bind1st(1,Add()));

for_each(v2.rbegin(), v2.rend(), Out(cout));cout<

return 0;

}

Program outputs:

A1 2 3 4 5 6 7 8 9 10

B2 3 4 5 6 7 8 9 10 11

C10 9 8 7 6 5 4 3 2 1

D11 10 9 8 7 6 5 4 3 2

The transform function is doing the heavy lifting here!

I thought it would give a compilation error, but I guess not?

Lorean 12 months ago

Wait, how does it add 1 to each element?

Tawna 12 months ago

Definitely B, I agree!

Salome 12 months ago

The output will be 2 3 4 5 6 7 8 9 10 11.

I feel like the output should be the original array incremented by 1, so maybe option B is correct? But I'm not completely confident.

I practiced a similar question where we used `for_each` and `transform`, but I can't recall if the output was reversed like this one.

I'm not entirely sure, but I remember something about `bind1st` being deprecated. Does that mean there could be a compilation error?

Gracia 1 year ago

I think the `transform` function is supposed to add 1 to each element in `v1`, so maybe the output should start from 2?

I'm a bit confused on this one. The options all seem to be Fibre Channel-related, but I'm not totally sure how they map to the requirements. I'll need to review my notes on virtualized storage and Fibre Channel features to try to figure this out.

I think for the Atlanta router, we need to set up a route for 2023::/126, but I'm not confident if it's pointing to 2012::1 or 2012::2.

I think Amazon CloudWatch would definitely be one of the services to track utilization metrics and errors, but I'm not sure about the second one.

Honestly, the specifics of group size and participation requirements can be confusing. I might be overthinking option B though.
