Features:

• Simple
• Machine Independent but Platform Dependent
• Mid-level language
• Rich library support
• Speed of execution
• Pointer and direct Memory-Access
• Object-Oriented
• Compiled Language

Applications of C++: 

• Operating Systems & Systems Programming. e.g. Linux-based OS (Ubuntu etc.)
