C++ vs C++0x vs C++11 vs C++98

C++98 was the first edition of the C++ standard. It had defined all the basic language constructs, the STL, and the standard library.

C++03 was the next revision to this standard. This was majorly a considered a bugfix for the standard as it corrected 92 core language defect reports, 125 library defect reports, and included only one new language feature: value initialization.

C++0x was the name of the work in progress that was expected to complete by 2008-09 but finally completed in 2011.

C++11 was the modern C++ standard published in 2011. This brought many major extensions and improvements to the existing language. Following are the major features of C++11 −

• Initializer lists
• Automatic type deduction
• Rvalue references and move constructors
• constexpr – Generalized constant expressions
• Modification to the definition of plain old data
• Uniform initialization
• Range-based for loop
• Lambda functions and expressions
• Alternative function syntax
• Explicit overrides and final
• A constant null pointer, nullptr
• Strongly typed enumerations
• Right angle bracket not being treated as an operator at appropriate places

• And many more. You can get the complete list with examples at https://en.wikipedia.org/wiki/C%2B%2B11.
