Tīmeklis2024. gada 11. jūl. · 4 Answers. You can move the index into the lambda capture and make the lambda mutable like this (requires C++14): std::generate_n (std::back_inserter (lst), N, [&func, idx = -1] () mutable {idx++; return func (idx);}); Now you can omit the line int idx = -1;. There might be a better solution though, as sacrificing the default const ... Tīmeklis总第38篇. 本文要主梳理STL中Lambda表达式的定制操作及常用的基本算法的实现方式。. 1.Lambda表达式的定制. 很多算法都会比较输入序列中的元素以达到排序的效果 …
