# C-programm-to-3-address-translator

  
It takes a subset of C programming language and generates intermediate (3 address)  code .


### Subset of C programming language is defined as below

		 Binary Operators: + , - , * , / ,exponentiation operator (denote it as @) 

		 Data types:  int , unsigned , signed , bool , float 

		 Bitwise operators : | , & , ~ , ^(XOR) 

		 Logical Operators : || , && , ! 

		 Relational Operators : ==, !=, <, <=, >, >= 

		 Assignment Operators : = , += , -= , *= , /= 

		 Unary opeartors : + , - 

		 Postfix / Prefix Operators : ++ , -- 

		 Identifiers:Simple identifiers without special characters (starts with alphabet)

		 

##### Control Structures:

		 Assignment Statement 

	 	 Expressions: 

	 	 	  infix expressions 

		 Iterative  

		 Conditional: 

			  if-else

			  else-if

			  switch 

		 Repetitive: 

			  while

		 Jump :

	  		  continue

	  		  break

###### Note:

          It follows C operators precedence , syntax rule.

          There is no scope rule  for identifiers .

          There is no function call.

          Functions shouldn't have argument(s).

          It reports following error messages

			lval requirement

			case  label duplication

			Variable is not defined  

			Redeclaration of variable

# I/O

         Input  

   			 -  C program which follows synatx rule as described above

         Output

   			 -  3 address code , Output will be displayed on  terminal/cmd and it's also available in file output.txt
