C++ Speed and Control

1.

C++
Speed and control since 1979
[Your name] · English class

2.

A short history
1979
1985
C++11
C++26
Bjarne Stroustrup
starts “C with
Classes” at Bell Labs
First commercial
version appears
C++98, C++11,
C++20: new tools
with every update
The newest
standard, with the
same goal: speed
and control

3.

Strict syntax, smart cleanup
Every statement ends with
;
Code blocks sit in { }
Every variable has a type
RAII
An object takes what it needs when it is created, and gives it back when it is destroyed.
Smart pointers mean no manual delete.

4.

One language, four styles
Procedural
Like C
Objectoriented
Generic
Functional
With templates
With lambdas
With classes
High-level, but with direct access to memory and hardware: fast and expressive.

5.

Where speed really matters
Operating systems
Browsers
Game engines
Windows, Linux
Chrome, Firefox
Unreal Engine
Databases
Embedded systems
Compilers
Fast data handling
Robots, medical machines
Even for other languages

Strengths and weaknesses
Good sides
Bad sides
• Speed
• Control over memory
• Huge set of libraries
• Stability: old code still works
• Hard to learn
• Easy to make memory mistakes
• Slow to compile

7.

The future looks strong
C++26
C++29
Reflection, better vectorization, async tools
Planned “profiles” for safer memory
C++ is not dying. It is changing to become safer while
staying fast.
