Features of C Language

Image
Features of C Language C is the widely used language. It provides many  features that are given below. Simple Machine Independent or Portable Mid-level programming language structured programming language Rich Library Memory Management Fast Speed Pointers Recursion Extensible 1) Simple C is a simple language in the sense that it provides a  structured approach  (to break the problem into parts),  the rich set of library functions ,  data types , etc. 2) Machine Independent or Portable Unlike assembly language, c programs  can be executed on different machines  with some machine specific changes. Therefore, C is a machine independent language. 3) Mid-level programming language Although, C is  intended to do low-level programming . It is used to develop system applications such as kernel, driver, etc. It  also supports the features of a high-level language . That is why it is known as mid-level language. 4) S...

C can also be defined has

C can be defined by the following ways: Mother language System programming language Procedure-oriented programming language Structured programming language Mid-level programming language 1) C as a mother language C language is considered as the mother language of all the modern programming languages because  most of the compilers, JVMs, Kernels, etc. are written in C language , and most of the programming languages follow C syntax, for example, C++, Java, C#, etc. It provides the core concepts like the array, strings, functions, file handling, etc. that are being used in many languages like C++, Java, C#, etc. 2) C as a system programming language A system programming language is used to create system software. C language is a system programming language because it  can be used to do low-level programming (for example driver and kernel) . It is generally used to create hardware devices, OS, drivers, kernels, etc. For example, Linux kernel...

Flow of C program

Image
Flow of C Program The C program follows many steps in execution. To understand the flow of C program well, let us see a simple program first. File: simple.c #include <stdio.h>      int  main(){     printf( "Hello C Language" );     return  0;    }   Execution Flow Let's try to understand the flow of above program by the figure given below. 1) C program (source code) is sent to preprocessor first. The preprocessor is responsible to convert preprocessor directives into their respective values. The preprocessor generates an expanded source code. 2) Expanded source code is sent to compiler which compiles the code and converts it into assembly code. 3) The assembly code is sent to assembler which assembles the code and converts it into object code. Now a simple.obj file is generated. 4) The object code is sent to linker which links it to the li...
