transpilers, + llvm can do this, so can discuss c++ -> C. c++ -> IR -> C
cpp uses libstdc++, equiv of glibc
C++: frame as bare metal and hosted c++, and stdlibc++ or whatever it is called.
is there a concept of freestanding C++? + manually write eg new, delete, what other functions? + yes hosted c++ and freestanding c++ exist as concepts, but linux kernel just written in c, not c++, so leave?
late binding a thing which c++ does which c doesn’t? "virtual". can have some objects which are not known at compile time?
c++: + passing arrays to functions. what is passed? reference ot first? length separately? + repeating an array n times
later on c++, different c++ standard library implementations. are various.
big thing on closures in c++? nested functions. are located on the heap not the stack? check?
new array and linked list type things + concatenation + slice/filter + insert + pop + traverse + map + sort + reverse
new keywods: + virtual + noexcept + override + const after function declaration
getters and setters
page on memory allocation on heap in c++, after c standard library
iterating over a string
operator overloading
changes to c standard library: printing "this" keyword in structs, classes (in methods)
algorithm header file (standard c++ library?) has for_each function. functional related?
h3 on functional programming currying std::transform. can do simple functional? functors lambda std::bind (partial function application)
partial functions in h3 section on functional
something on polymorphism (can be done in the context of structs)
parallel threads
#include<thread> // std::thread
void foo();
void bar(int x);
// Carries on after starting thread
std::thread first (foo)
std::thread second (bar, 0)
// Following waits for threads to finish
first.join();
second.join();structs still exist, but objects can be used instead
dynamic name binding on derived objects?
encapsulation?
how methods talk to each other. encapsulation
class templates operator overloading. eg can make "+" do something for custom class
public methods and private methods
creating inherited class c++, inherit from multiple?
messages are sent betweeen objects. via inheritance?
motivation behind OOP. global state leads to problems. answers are objects oriented or functional.
h3 on standard library. page on use of c standard library. page speciifcally on malloc to new. on << and >>?
Shared pointer Unique pointer weak pointers smart points
smart pointers do reference counting. do any others?
vector as data type + part of c++ standard library, not in regular c
