Why we select C++ first time?

First language we learn in university Some expressions seems to be elegant Dozens of “cool” features! Cool it has operator overloading! Shorter expressions than ones from Pascal All benefits of C and more! All benefits of Java OOP and more! It can do everything Java can but faster!

Problems

Learning curveHighest cost of error

Mixed abstraction levelsNo modules

No package managerInsane Metaprogramming

stl is too low levelBest libraries are crazy complicated (boost, Eigen)

Hard to find library you need

Mixed abstraction levels:

You can write asm inline code You can use pointers

You can use C style allocationYou can use OOP

You can use lambda closuresAnd you can do it at the same time!

No modules:

Long compilation timeCompile all the library per CPP

No module encapsulationOld-school preprocessor

Namespace crutchHard to develop package manager

No package manager:

Benefits (development):

We can write fast upper level codeWe can write low level code if we need one

Hardcore speed optimizationHardcore memory usage optimization

RAIITemplates are real not just polymorphic wrappers

Real time softwareVery good optimizing compilers

Benefits (architecture):

Predictable memory usagePredictable reaction time

Embeddable almost anywhereA lot of code already written in C and C++ can

be usedCan write low level code (device drivers,

controllers)
