实际上,vbptr 指的是虚基类表指针(virtual base table pointer),该指针指向了一个虚基类表(virtual table),虚表中记录了虚基类与本类的偏移地址;通过偏移地址,这样就找到了虚基类成员,而虚继承也不用像普通多继承那样维持着公共基类(虚基类)的两份同样的拷贝,节省了存储空间。
Xmake Version v2.8.9+HEAD.cb1b65054 Operating System Version and Architecture Windows 10 21H2 Describe Bug The ZmqPb library needs protobuf and zmq, and for that, since #3576, it also installs abseil. That just doesn't work and exits(1) ...
From 2019 to 2023, the shared CPP contribution rate went from 9.9% to 11.9% (up to that year’s YMPE). Starting in 2024, the government has raised the amount of income considered for a “full YMPE year”. Over two years, a 14% increase will be phased in. Basically this will ...

CPP income is indexed to the Consumer Price Index All-Items Index. Every January, benefit rate increases are calculated to make sure CPP retirement benefits keep up with cost of living increases. From 2022 to October 2023, CPP was increased from an average of $702.77 to $758.32 per month. ...
用在member function,那么调用的时候不会传入thispointer,只能处理类的staticdata member,调用的方式有两种:Account::set_rate();或者通过 instance 调用a.set_rate(),这个时候编译器就不会帮我们传入this 单例模式:这个类只有一个对象,放到 static function 里管理 ...
今天就给大家介绍下在R中如何直接调用C++的函数进行数据的计算。在这里需要用到的包是Rcpp。此工具包中有四个核心的包：RcppArmadillo使得线性代数的引入语法更加接近matlab；RcppEigen 高优化的线性代数计算；RInside实现在C++中调用R代码；RcppParallel基于Rcpp实现计算的并行运算。我们首先看下包的安装：
avoid local minima when using handcrafted STFT and iSTFT filterbanks, we initially begin training the models for 3 epochs with batch size 16 using stochastic gradient descent (SGD) with Nesterov momentum 0.6 and learning rate 1e-3 before switching to the AdamW optimizer until reaching 100 epochs...
