The project is supposed to read a calculation expression and produce a three-address code in C Language.

The project has been divided into three phases.

flowchart TD;
    A[Compiler]--Phase 1-->B[Lexical Analysis];
    A[Compiler]--Phase 2-->C[Syntax Analysis];
    A[Compiler]--Phase 3-->D[Intermediate Code Generation];

Running

Phase 1

  flex  lex.l
  gcc   lex.yy.c
        a.exe

Phase 2

  bison -d -y   yacc.y
  gcc           y.tab.c
                a.exe

Phase 3 (Project)

  bison -d -y       yacc.y
  flex              lex.l
  gcc   lex.yy.c    y.tab.c
                    a.exe
