WebApr 8, 2024 · You can always put your arguments in a struct and use a lambda to unpack them for the function call. Or, if you have vectors full of values, use std::iota () and the index in the lambda. Hi @ypnos, I don't want extra storage of order n. Struct will duplicate storage of the four vectors.

WebThe vector is extended by inserting new elements before the element at the specified position, effectively increasing the container size by the number of elements inserted. This causes an automatic reallocation of the allocated storage space if -and only if- the new vector size surpasses the current vector capacity. Because vectors use an array as …
