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

#include

using namespace std;

int main(){

int t[] ={ 3, 4, 2, 1, 6, 5, 7, 9, 8, 0 };

vector v(t, t+10);

map m;

for(vector::iterator i=v.begin(); i!=v.end(); i++) {

stringstream s; s<<*i<<*i; m.insert(pair(*i,s.str()));

}

for(map::iterator i=m.begin();i!= m.end(); i++) {

cout<<*i<<" ";

}

return 0;

}

Aprogram outputs: 3 4 2 1 6 5 7 9 8 0

Bprogram outputs: 00 11 22 33 44 55 66 77 88 99

Cprogram outputs: 0 1 2 3 4 5 6 7 8 9

Dprogram outputs: 0 00 1 11 2 22 3 33 4 44 5 55 6 66 7 77 8 88 9 99

Compilation error? Nah, I don't think so.

Becky 11 months ago

I think it's D, but I'm not 100% sure.

Basilia 11 months ago

Wait, why would it output "00 11 22"? Seems off.

Flo 11 months ago

Definitely not option A, that's for sure!

Alva 11 months ago

Looks like it outputs pairs of numbers.

Daniel 12 months ago

I’m leaning towards option D because it seems like it would print each number twice, but I’m worried I might be mixing up the logic.

Patrick 12 months ago

I feel like the output might be the pairs of numbers concatenated together, so maybe option B? But I'm not entirely confident.

Nettie 12 months ago

I remember a similar question where we had to output values from a map, but I can't recall if it was in order or not.

Marg 1 year ago

I think the program should compile fine since all the includes seem correct, but I'm not sure about the output.

Alyce 1 year ago

Ugh, I hate questions that involve string manipulation. Let me re-read this a few times and see if I can spot the pattern.

Glendora 1 year ago

This seems straightforward enough. I'm pretty confident I can work through this and arrive at the correct answer.

Melissa 1 year ago

I'm a bit confused by the map and vector usage here. I'll need to review my notes on those data structures to make sure I'm following the logic.

Cassie 1 year ago

Hmm, this looks like a tricky one. I'll need to carefully step through the code and think about how the data structures are being used.

Nickole 1 year ago

Okay, I think I've got a handle on this. The key is understanding how the stringstream is being used to convert the integers to strings.

Rose 1 year ago

Hmm, I'm a bit unsure about this one. I know awk is a powerful text processing tool, but I can't recall what it's specifically based on. I'll have to think this through carefully.

Lea 1 year ago

Hmm, I'm a bit unsure about this one. The question mentions hiring an external writer, so I'm not sure if that's considered avoidance, transference, or something else. I'll need to think this through carefully.

Aretha 1 year ago

Haha, are they trying to trick us? This seems too straightforward to be the right answer.

User 3: Yeah, it does seem too straightforward, but I'm going with B) as well

User 1: I think the answer is B) program outputs: 5 7

Tom 1 year ago

Wait, what? I thought I had this figured out, but now I'm second-guessing myself. Better read the code again.

Denny 1 year ago

↳ replying to Tom

User 3: The output will depend on the order of elements in the map. Let's analyze it further.

Donte 1 year ago

↳ replying to Tom

User 2: It looks like the program is inserting each element twice into the map.

Charlene 1 year ago

↳ replying to Tom

User 1: The code is inserting elements into a map based on the vector values.

Ozell 1 year ago

Aha, I know this one! Gotta love those stringstreams and map insertions.

Janine 1 year ago
