Mostly Asked Questions from C Language:-




Q 1) What are the key features in the C programming language?

  • Portability: It is a platform-independent language.
  • Modularity: Possibility to break down large programs into small modules.
  • Flexibility: The possibility of a programmer to control the language.
  • Speed: C comes with support for system programming and hence it compiles and executes with high speed when compared with other high-level languages.
  • Extensibility: Possibility to add new features by the programmer.
