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

#include

using namespace std;

void print(int v) { cout<

struct Sequence {

int start;

Sequence(int start):start(start){}

int operator()() {

return 10*(1+(start++ %3));

}

};

int main() {

vector v1(10);

generate_n(v1.begin(), 10, Sequence(1));

remove(v1.begin(), v1.end(), 10);

for_each(v1.begin(), v1.end(), print);cout<

return 0;

}

Program outputs:

A20 30 10 20 30 10 20 30 10 20

B20 30 20 30 20 30 20

C20 30 20 30 20 30 20 30 10 20

Sequence class is pretty clever, love how it works!

Definitely not a compilation error, so that's wrong.

Galen 12 months ago

Wait, does it really generate 10 values? Sounds odd.

Tyisha 12 months ago

I think it should be option B instead.

Jesusita 12 months ago

The output will be 20 30 10 20 30 10 20 30 10 20.

I’m worried there might be a compilation error because of the way the `start` variable is being modified in the `operator()`.

I feel like the output will be option B, but I might be mixing it up with another question we practiced.

I remember something similar where we used `generate_n`, but I can't recall how the `Sequence` struct affects the output.

Jamal 1 year ago

I think the code should compile fine since it uses standard libraries correctly, but I'm not sure about the output.

Hmm, I'm a bit confused about the "suppression data set" option. Is that really necessary for Einstein Vision to work properly? I'm not sure about that one.

Hmm, I'm a bit confused on this one. I know EVC is used to enable live migration between hosts with different CPU types, but I'm not sure what the specific requirements are for setting it up. I'll have to think this through carefully.
