I thought it might run fine, but now I’m not so sure.

Fabiola 1 month ago

I’m leaning towards option C too. It just doesn’t make sense.

My 2 months ago

No way, it won't compile. Line 8 is definitely an issue.

Levi 2 months ago

I feel like it should output 5 4 3 2 1.

Gladys 2 months ago

Yeah, I agree. The order of parameters in assign is wrong.

Lorrine 2 months ago

I think it will give a compilation error in line 8.

Cassi 2 months ago

I think it's a runtime exception, not a compilation error.

Leonardo 2 months ago

Nope, it outputs 1 2 3 4 5 if it compiles!

Taryn 3 months ago

Wait, really? I thought it would just print the numbers.

Aliza 3 months ago

Totally agree, you can't use `at()` on a list!

Lawanda 3 months ago

The program will actually have a compilation error in line 8.

Fernanda 3 months ago

I think it's option C for sure.

Gary 3 months ago

Nope, it outputs nothing because of that error.

Blythe 3 months ago

Wait, really? I thought it would just output the numbers.

Crista 5 months ago

Totally agree, you can't use `at()` on a list!

Jordan 5 months ago

The code will actually cause a compilation error in line 8.

Lourdes 6 months ago

I think the loop on line 8 could cause a runtime error since `l1.size()` might not work as expected with a list.

Krystal 6 months ago

I feel like there might be a compilation error because of the way `l1.assign` is used. It seems like the parameters are in the wrong order.

Jamika 6 months ago

I remember practicing a similar question where we had to use `assign`, but I can't recall if the order of parameters matters.

Mica 6 months ago

I think the code should compile fine, but I'm not sure about the output since the `assign` method seems a bit confusing.
