difference in c and c++ code example

Example: c vs c

C++ compiles into machine code, while C# compiles to CLR, which is interpreted by ASP.NET.
C++ requires you to handle memory manually, but C# runs in a virtual machine which can automatically handle memory management.
C# does not use pointers, while C++ can use pointers anywhere.
C++ can be used on any platform, though it was originally designed for Unix-based systems. C# is standardized but is rarely used outside of Windows environments.
C++ can create stand-alone and console applications. C# can create a console, Windows, ASP.NET, and mobile applications, but cannot create stand-alone apps.
