I agree, it should be 10 after casting!

Wait, is the output really 11? That seems off.

Pretty sure it rounds down to 10.

I think it will output 11 when cast to int.

It's definitely 10.501 as a float.

I’m leaning towards option D, but I’m confused about the initial float value. Did we cover how to handle floats with a leading question mark?

This seems similar to a practice question we did last week. I believe it should output 11 because of how rounding works in C++.

I think the output should be the integer part of the float, so maybe it's 10? But I'm not completely confident.

I remember we discussed type casting in class, but I'm not sure how the float will convert to an int here.

I've got this! The float 10.501 will be truncated to 10 when cast to an int. The output should be 10.

I'm a bit confused here. Does the type casting round the value or just truncate it? I'll have to double-check the behavior.

Okay, let me walk through this step-by-step. The float is initialized to 10.501, and then we cast it to an int. I think the output will be 10.

Hmm, this looks like a tricky one. I'll need to carefully think through the type casting from float to int.

This is a simple case of rounding. The float f is 10.501, and when we cast it to an integer, it should round up to 11. Option B is the correct answer, no doubt about it.

Haha, the question mark is just there to confuse us. It's a classic trick question! I'm going to go with option D, because who doesn't love a bit of chaos in their code?
