Discuss C++ Institute CPP Exam Topic 9 Question 96

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

#include

using namespace std;

int main(){

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

string first[] = {"three", "four", "two", "one", "six","five", "seven", "nine","eight"," ten"};

multimap m;

for(int i=0; i<10; i++) {

m.insert(pair(second[i],first[i]));

}

if (m[11] == "eleven") {

cout<<"eleven ";

}

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

cout<second<<" ";

}

cout<

return 0;

}

Aprogram outputs: one two three four five six seven eight nine ten 11

Bprogram outputs: one two three four five six seven eight nine ten 10

Cprogram outputs: one two three four five six seven eight nine ten 10

Dprogram outputs: eleven one two three four five six seven eight nine ten 10

Agreed, the condition with m[11] won't be true.

Sharika 11 months ago

Definitely outputs "ten" at the end, not "11".

Quentin 11 months ago

Wait, is there a compilation error? I’m not sure.

Carey 11 months ago

I think it outputs "eleven" if the condition is true.

Lonny 11 months ago

The code will compile fine, no errors.

Brandee 12 months ago

I feel like the output should be the strings in order, but I'm confused about the last line. Does it really print the size of the map?

William 12 months ago

I practiced a similar question where we had to check the size of a map, but I can't recall if the output would include "eleven" or not.

Mozell 12 months ago

I remember something about how `multimap` doesn't support the `[]` operator like `map` does, so maybe there's a compilation error?

Dean 1 year ago

I think the code should compile fine since all the syntax looks correct, but I'm not sure about the multimap access with `m[11]`.

Jamal 1 year ago

I'm a bit unsure about the behavior of accessing a multimap element with an index that doesn't exist. That could be the key to solving this.

Odelia 1 year ago

Okay, I think I've got a handle on this. Let me work through the logic and see if I can determine the output.

Adrianna 1 year ago

Hmm, the multimap insertion and iteration seems straightforward, but that if statement with m[11] has me a bit confused.

Emilio 1 year ago

This looks like a tricky one. I'll need to carefully step through the code to understand what's happening.

Talia 1 year ago

I'm feeling pretty confident about this one. I'll work through it step-by-step and double-check my understanding before submitting my answer.

Tamekia 1 year ago

This looks like a straightforward question about organizing data in a tabular format. I think the key is to identify the FlexCard feature that allows for grouping and filtering by case status.

This code is so complicated, I'm just going to guess. I'll go with A. The program outputs one two three four five six seven eight nine ten 11, because that's the most random-sounding answer. Hey, at least I'm honest about my guessing!

I agree, the program will output one two three four five six seven eight nine ten 10.

Mose 2 years ago

I think the correct answer is B, based on the code logic.

True, it's always better to understand the code first.

Guessing is not a good idea when it comes to coding.

France 2 years ago

This is a tricky one, but I think the answer is E. The program will throw a compilation error because the code is trying to access the multimap with an index of 11, which is not a valid key in the multimap.

Ona 2 years ago

Hmm, I'm not sure about this one. I'm going to go with C. The program outputs one two three four five six seven eight nine ten 10, because that's what it looks like the code is doing.

Mitzie 2 years ago

↳ replying to Ona

I'm not sure either, but I think it might be A. The program outputs one two three four five six seven eight nine ten 11.

Frankie 2 years ago

↳ replying to Ona

No, I disagree. It's definitely B. The program outputs one two three four five six seven eight nine ten 10.

Vicente 2 years ago

↳ replying to Ona

I think it's actually D. The program outputs eleven one two three four five six seven eight nine ten 10.

Rebecka 2 years ago

I think the answer is D. The program will output eleven one two three four five six seven eight nine ten 10, because the if statement checks for the value 11 in the multimap, which will be true and print 'eleven'.

Nell 2 years ago

Oh, I see. Thanks for clarifying.

Lourdes 2 years ago

↳ replying to Rebecka

No, the correct answer is B.

Glynda 2 years ago

I'm not sure, but I think the program will compile without errors and output one two three four five six seven eight nine ten 10.

Maricela 2 years ago

I agree with Filiberto, the program should output one two three four five six seven eight nine ten 10.

Vallie 2 years ago

The correct answer is B. The program will output one two three four five six seven eight nine ten 10, as the multimap will contain the values from 1 to 10, and the size of the multimap will be 10.

Sang 2 years ago
