1)从容器中擦除所有比较等于value的元素。等价于returnc.remove_if([&](constauto&elem)->bool{returnelem==value;});。 2)从容器中擦除所有满足pred的元素。等价于returnc.remove_if(pred);。 参数 c-要从中擦除的容器 value-要擦除的值 pred-若应该擦除元素则返回 true的一元谓词。
通过源码查看,可以发现front()其实是引用类型,而std::erase本身又调用了std::__remove_if,这也不难让人想出解决问题的办法,也就是做一份拷贝。 voidmy_erase(auto&x){autotmp=x.front();std::erase(x,tmp);} 但是既然都来写Cpp了,我们还可以追求点“洁癖”,我们很多时候并不希望有多余...

I have suspicions 2022 might havetwangedsomething with 2019 out of whack. That happened when I was using 2017 as my primary IDE and tried a preview of 2019. Trying to repair the mess was horrendous and time consuming. Eventually I had to resort to a complete slash-and-burn-remove-it-com...

False if this type represents an l-value reference. This API was introduced in Visual Studio 14 Update 2 (DkmApiVersion.VS14Update2). IsUnloaded Returns true if a 'unloaded' event has been raised for this object (example: DkmThread::Unload is called) or if the obj...
