Similarities and Differences between Ruby and C++
There are many similarities between C++ and Ruby, some of them are: Just like C++, in Ruby…
- As in C++, public, private, and protected works similarly in Ruby also .
- Inheritance syntax is still only one character, but it’s < instead of : in Ruby.
- The way ‘namespace’ is used in C++, in the similar way we may put our code into “modules” in ruby.
- There are many similar operators found in Ruby as found in C++.
- Though the keyword names have been changed to protect the innocent, exceptions work in a similar manner.
Difference between Ruby and C++.
|1.||In Ruby, every variable is just an automatically dereferenced name for some object which means that there is no explicit references in Ruby.||Unlike Ruby there is explicit references in C++.|
|2.||Yukihiro Matsumoto, also known as “Matz,” developed Ruby in Japan.||Bjarne Stroustrup introduced C++ in 1979 at Bell Labs as an expansion of the C language.|
|3.||First release Ruby 1.0: December 25, 1996||First C++ release in October 1985|
|4.||Objects are strongly but dynamically typed in Ruby.||Objects are not strongly typed as that in Ruby.|
|5.||The “constructor” is called initialize instead of the class name.||This is not the case in C++.|
|6.||Array and Hash are only two container types.||There are many container types in C++.|
|7.||There’s no need of C++ templates. No casting either required.||C++ templates are necessary here. Casting is there.|
|8.||It’s self instead of this.||It is this instead of self.|
|9.||Iteration is done a bit differently. In Ruby, you don’t use a separate iterator object. Instead you use an iterator method of the container object that takes a block of code to which it passes successive elements.||Vectors are required and used in C++ which makes the coding easy.|
|10.||lib, a unit testing, comes standard with Ruby.||This is not available with C++.|
|11.||There’s no type conversions in Ruby.||Type conversion is necessary in C++.|
|12.||There are some enforced case-conventions.||No such case conventions are present in C++ which makes it easy.|
|13.||You can re-open a class anytime and also you can add more methods in Ruby.||We cannot do this in C++.|
|14.||Some methods end in a ’?’ or a ’!’ in Ruby. It’s actually part of the method name.||No such symbols are required at the end of methods in C++.|
|15.||All methods are always virtual in Ruby.||Methods are not virtual in C++.|
|16.||Multithreading is built-in, but as of Ruby 1.8 they are “green threads” as opposed to native threads.||Multithreading is not built-in in case of C++.|
|17.||Parentheses used for calling of method are usually optional in Ruby.||Parentheses are required in C++ and it is necessary.|
|18.||You don’t directly access member variables—all access to public member variables is via methods.||Member variables in C++ can be access directly.|
|19.||Ruby is mainly used to build web applications build servers and data processing, web scraping, and crawling.||C++ is mainly used for Operating systems, Mobile applications, Web browsers, Healthcare and research computation, Telecommunications, Databases, Internet of Things (IoT) devices, Game development, Google search engine, etc.|
|20.||Ruby supports operating systems such as Linux, macOS, Solaris, and FreeBSD.||C++ supports operating systems such as Apple OS X, Windows 95, 98, 2000, XP, Symbian OS, and BeOS.|
