## About

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.

    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

```
