Lambda表达式可以使用条件表达式进行复杂的逻辑判断,例如实现多种排序规则: auto custom_sort = [](bool ascending) { return [ascending](int a, int b) { return ascending ? a < b : a > b; }; }; std::vector<int> numbers = {3, 1, 4, 1, 5, 9, 2, 6, 5}; std::sort(numbers.begi...
If the lambda does not fit on the same line as the definition, use the braced syntax.public class Foo { private int _bar; public Foo(int bar) => _bar = bar; public int Bar => _bar; }[F.4.9] ✔️ DO Use braces with lambda expressions that span multiple lines...
如果是用Linux学习,需要先安装GCC、make等工具。Ubuntu上安装命令如下: sudo apt install gcc g++ make 如果是用Windows,需要先装有编译工具。建议安装MinGW环境进行学习(用Visual Studio也可以,但是用来学习cmake的话感觉有点笨重),本课程用的编译工具是MinGW,能和课程工具保持一致最好。 MinGW常用有以下两个版本,选...

I have a long series of recent articles in my blog about how a subtle difference between lambda and anonymous method binding led to me having to rewrite HUGE amounts of the compiler to get it working correctly. Mads Torgersen[MSFT] (Expert): Q: We're doing a lot of work with Excel/...
