Intermediate C++ Game Programming Tutorial 16
From Chilipedia
In the video we take a look at a couple of bangers from <algorithm>
, and we learn what lambda functions are and how to use them.
Contents
Topics Covered
- Algorithms
std::sort
andstd::remove_if
- Concepts (as in, type concepts like Comparable)
-
<functional>
functors as predicates - Lambda functions
Errata
In the video Chili states that std::remove does not preserve the relative order of elements in the container, but this is fake news! Relative order is preserved: [1]

Homework
Solve the problems in Source.cpp attached below using the <algorithm> library and other parts of the standard library as extensively as possible. As a bonus problem, implement the sprite drawing effect shown at the end of the video using a lambda function.
