If I want to read all integers from standard input to a vector, I can use the handy:But let's assume I only want to read n integers. Is the hand-typed loop everything I got?

## How to erase value from vector of struct using erase-remove idiom?

How to erase all values from vector of struct, where struct value k equals to 0?I have tried to andI guess what you want to do is to remove all objects that have k==0, so create a lambda for that:

## How to keep dropping the first value, until the sum of the vector is less than 20?

I am looking for a function which takes a vector and keeps dropping the first value until the sum of the vector is less than 20. Return the remaining values.

## Change vector type using constructors?

I have a vector full of integers. I have a class that takes an integer as a constructor. I want to create a new vector full of such class, using the values in the first vector as a constructor for each.

## Does std::find on empty vector cause undefined behaviour?

trying to find an info on what happens if an empty vector used during std::find but didn't had much luck finding any info.

## Count repeating integers in an array

If I have this vector:I would like to get the position of each unique number according to itself.At the moment I'm using:

## Count consecutive elements in a same length vector

If I have a vector likeHow can I generate a vector of the same length containing the count of consecutive elements, like so:

## Mapping a vector to specific range

I have a standard vector contains, for example, the following elements[-6, -7, 1, 2]I need to map these elements to the range from 1 to 4. i.e I need the vector to be like this

## How do vector elements preserve their original address after a vector std::move?

As you can see in the output, the objects of the vector pre not only "moved" to the vector post, but also preserved their original address space in memory. What is really going on behind this move? Is this behaviour expected? Say I need to have a separate vector of...
