containers

问题 I wasn't able to find straight answer, to this question, but here it is: Let's say that I have a host which has max open files 1024: [root@host]# ulimit -a open files (-n) 1024 and a docker container running in that host with: [root@container]# ulimit -a open files (-n) 1048576 So will I have a problem in container if I try to open more then 1024 files? I think real limit in this case for container will be 1024 files. What do you think? 回答1: Although its a little bit late, I just want to

问题 Is there a scenario where the container is not iterable, according to this graph? 回答1: Depends on what you mean by always . According to collections.abc a container is an object that implements __contains__ method an iterable is an object that implements __iter__ (or __getitem__ , as a fallback) So, theoretically, no, you can implement a container that is not an iterable. However, all standard python containers (and most containers implemented by libraries) are also iterable. 来源： https:/

问题 I need to create a stl::set of structures. Therefore, I wrote the following: stl::set <Point> mySet; // Point - name of the structure. Then I tried to add a structure instance to mySet as follows: Point myPoint; mySet.insert(myPoint); However, I get several compilation errors (error C2784, error C2676): 1>C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\xfunctional(125): error C2784: bool std::operator <(const std::vector<_Ty,_Ax> &,const std::vector<_Ty,_Ax> &): failed to bring

问题 I have a console application that is built on .NET Framework v4.8. I am trying to run it in Azure Container Instances(ACI) using the docker image. I have created a docker image locally and pushed it to ACI and it is running successfully. Now I am facing one issue. This application sends an email with RDLC reports. But the reports I am getting in the mail have different fonts than the report I am getting previously(without docker). I found that the base docker image mcr.microsoft.com/dotnet

问题 #include <map> ... multimap<char,int> first; first.insert(pair<char,int>('a',10)); first.insert(pair<char,int>('b',15)); first.insert(pair<char,int>('b',20)); first.insert(pair<char,int>('c',25)); Say I now want to remove one of the pairs I have just added to the map. I have examples to remove an entire key entry, which for key 'b' would remove both 'b',15 and 'b',20. But what is the code to remove just, say, the pair 'b',20? 回答1: You can use std::multimap<char, int>::equal_range , which will
