Which level the C language is belonging to

S.no
High Level
Middle Level
Low Level
1High level languages provides almost everything that the programmer might need to do as already built into the languageMiddle level languages don’t provide all the built-in functions found in high level languages, but provides all building blocks that we need to produce the result we wantLow level languages provides nothing other than access to the machines basic instruction set
2Examples:
Java, Python
C, C++Assembler

C language is a structured language

S.no
Structure oriented
Object oriented
Non structure
1In this type of language, large programs are divided into small programs called functionsIn this type of language, programs are divided into objectsThere is no specific structure for programming this language
2Prime focus is on functions and procedures that operate on dataPrime focus is on the data that is being operated and not on the functions or proceduresN/A
3Data moves freely around the systems from one function to anotherData is hidden and cannot be accessed by external functionsN/A
4Program structure follows “Top Down Approach”Program structure follows “Bottom UP Approach”N/A

Examples:
C, Pascal, ALGOL and Modula-2
C++, JAVA and C# (C sharp)
 BASIC, COBOL, FORTRAN

Key points to remember:

  1. C language is structured, middle level programming language developed by Dennis Ritchie
  2. Operating system programs such as Windows, Unix, Linux are wriiten by C language
  3. C89/C90 and C99 are two standardized editions of C language
  4. C has been written in assembly language
