Nettet6. des. 2012 · int a = 0; because I find it more clear and it's more widely used in practice. This applies to your code, where the type is int. For class-types, the first is copy-initialization, whereas the other is direct-initialization, so in that case it would make a difference.

Therefore, y ∈ f ( A) ∩ f ( B). This shows f ( A ∩ B) ⊆ f ( A) ∩ f ( B). Directly by definition you can prove it. Let y ∈ f ( A ∩ B). (This is because X ⊂ Y means every element of X is of Y; so to prove X ⊂ Y we take an arbitrary one out of X to see if that one is in Y .)
Nettet两个都是对的: 都是建立数组,只不过数组初始化方式不一样 int a[5]={}; 全部数组元素使用默认值,当然默认值一般是0; int a[5]={0}; 第一个元素初始化为0,其他使用默认值(默认值也是0) 发布于 2024-03-05 09:52 赞同 2 添加评论 分享 收藏 喜欢收起 Nettet2 timer siden · NAPLES, Fla., April 14, 2024 (SEND2PRESS NEWSWIRE) — Kelly Roofing has completed the first-ever international Tesla Solar Roof installation, marking a significant milestone in green energy ...
