Introduction
C Langauge
- C is a powerful general-purpose programming language.
- C is a middle level language which can be used to perform High Level Operations as well as low level operations.
- C Language is used for system Programming i.e. to design programs to control the system.
- It can be used to develop software like operating systems, databases, compilers, and so on.
History
- C programming language was developed in 1972 by Dennis Ritchie at bell laboratories of AT&T (American Telephone & Telegraph), located in the U.S.A.
- It was developed to overcome the problems of previous languages such as B, BCPL, etc.
- Initially, C language was developed to be used in UNIX operating system. It inherits many features of previous languages such as B and BCPL.
Compiler
- Compiler is a program which converts high/middle level language source code into m/c code (i.e. low level instructions)
Types of C Compiler
- TCC
- GCC
TCC
- Turbo C Compiler is one of the basic and popular compilers for the C programming language.
- This was first introduced in 1987
- It was popular for its small size, compilation speed.
GCC
- GNU Compiler Collection is the compiler produced by the GNU Project.
- This supports many programming languages and is a free software foundation under the General Public License.
- This compiler was first released in 1987 and initially supported only C- Programming language.
C program Compilation Process
The compilation process in C is converting an understandable human code into a Machine understandable code and checking the syntax and semantics of the code to determine any syntax errors or warnings present in our C program. Compilation has to go through several phases of compilation (translation) to become an executable file that a machine can understand.
Source Code File
- This file contains our program.
- File extension is .c
Preprocessing
- It processes all preprocessor commands such as #include, #define etc.
- File extension is .i
Compilation
- The compiler converts preprocessed file into assembly code
- File extension is .s
Assemble
- The Assembler converts compiled assembly code into object code ( machine code)
- File extension is .obj or .o
Linking
- The Linker links library functions object code with our programs object code.
- File extension is .exe
