compare-func | Get a compare function for array to sort

I am attempting to generate a sorted vector std::vector> from a set of integer. By iterating the integer set, the value of the integer will be set to the first value of the pair and the second value of the pair will be computed by another function. All pairs should be sorted according to the second value in my final vector. To this end I have two plans to generated the vector: either I "insert" the pair to the correct position (by iterating from the vector begin and compare the second-value), or I simply do push-back and sort (by std::sort with some compare-function) the whole vector after all pairs have been pushed. So which plan would be more efficient? (Or there is an even better approach?)

I am using conventional changelog (https://github.com/conventional-changelog/conventional-changelog) to generate a changelog based on commits, within an Angular app.

I Work with bitbucket, and so the default template won't work. So I used the custome template feature. My problem is the line return are not generated. I don't know if the issue comes from my template, my config or the default conventional-changelog, including
or double space won't work.

so here is an exemple output

Boost documentation and previous stack overflow both give working examples of how to define custom comparator functions and include handle in the node type of a boost heap. However when I combine both of these features (a custom defined compare function and a handle within the node type) I get errors reporting invalid use of incomplete type of 'struct compare_Node'.

Other than predefining both structs of Node and compare_Node I'm not sure to solve the circularity while still holding the handle's safely as a member within the Node struct.

This has been confusing me for sometime, not sure if someone can understand what I am trying to drive at

I am trying to figure out what exactly does passing cmp as the argument into buildHeap does

I want to make a template class and pass it a compare function. I found a great answer on this link

Unfortunately when I made a template class called "WaitingQueue" and passed the compare function in the constructor of the class(in class foo), the code does not compile and throws error: "'compare' is not a type".

I cannot understand the error here. The code in the link above runs without error. Can anyone please tell me what I have done wrong here? Thanks in advance

Consider the template function sort(...) below. This is a wrapper function around std::sort. The purpose is to provide a better syntax when sorting vectors of user-defined classes. The first argument is the vector to be sorted. The second argument is a function specifying how the vector is to be sorted (on which public member variable or function).

std::sort require a compare-function in order to rank the different items in the vector. This is declared as a lambda inside my sort-function. However, this code only compiles if the lambda is declared 'auto', not if it is declared as bool. I find this strange. Could someone please explain?

(The code should compile as it stands now. To observe the problem, uncomment the line beginning with 'bool').

We have some old classes using Contnrs.TObjectList, and in some cases custom compare-functions are used to sort these lists, using something like this:

I have applied the accepted answer to this question in a templated class, like this:
