  2. It was developed at Bell Laboratories in 1972 by Dennis Ritchie.
  3. Why it is named as C ? There is no such logic behind the naming of C Language.
    It was developed to cover all the inabilities of B language (simplified version of BCPL). So, it was just named C as it is next to B in the English alphabets.
  4. C is the only programming language that exists for such a long period and still it is widely used.
  5. C is the basis of many other programming languages like C++, Java, JavaScript, Go, C#, PHP, Python, Perl, C-shell and many more.
  6. Unix was one of the first operating system kernels implemented in a language other than assembly and that was C.
  7. Previously, C was considered as the high level language but today many programmers consider it as a low level language as it supports only scalar operations.

  2. “sizeof” is the only operator which is also a keyword.
  3. In printf() and scanf(), f stands for formatted not function.
  4. Compiler doesn’t know header file, preprocessor processes these and expands souce code.
  5. Header file name can be included in 2 ways, (a) Using angular brackets (b) Using double inverted comma.
  6. Compiler generates assembly code not machine code and then assembler generates the machine code.
  7. sizeof operator cannot tell us the size of functions because this operator works on compile time and functions loads in memory at run time.
