Codes for Practical experiments of System Programming And Compiler Construction (Semester VI - Computer Engineering - Mumbai University)

Experiment List:

1. To create your own library using macros
2. To design lexical analyzer for a language whose grammar is known
3. To study and the implementation of lex and yacc tool (A)To implement LEX PROGRAMS using Dev-Cpp
4. To design and implement a program for LL(1) parser
5. To generate 3-address code as an intermediate code representation 6.(A)Implementation of Code Optimization Techniques (B)Implementation of Target code generation phase of the compiler
6. Implementations of two pass Macro Processor

1. Ensure you have Python 3.x installed on your machine. You can download it from Python's official website.
2. Ensure you have Flex(fast lexical analyzer generator) installed on your machine at "C:\GnuWin32". You can download it from Flex download link.
3. Ensure you have Bison(Yacc-compatible parser generator) installed on your machine at "C:\GnuWin32. You can download it from Bison download link.
4. Ensure you have Dev C++ installed on your machine at "C:\Dev-Cpp". You can download it from DEV C++ Download link.
5. Open Environment Variables and add "C:\GnuWin32\bin" and "C:\Dev-Cpp\MinGW64\bin" to path. (If the path is different, ensure you add the correct bin path)

1. Clone the repository

git clone https://github.com/riddhigupta1110/SystemProgrammingAndCompilerConstruction-VI-MU-CSE.git

2. Navigate to the project directory:

cd SystemProgrammingAndCompilerConstruction-VI-MU-CSE

You can run each Python program using any code editor or the command line:

Using Visual Studio Code:

1. Open Visual Studio Code.
2. Open the project folder (SystemProgrammingAndCompilerConstruction-VI-MU-CSE) in VS Code.
3. Open the desired .py file.\n
4. Run the program by pressing F5 or by clicking the "Run" button in the top-right corner of the editor.

• Lex Programming Basics
• Reference Video for downloading

1. Save your Lex files with “.l” extensions in any specific directory
2. Open Command prompt and switch to your working directory where you have stored your lex file (“.l“)

Use the following commands in the same order as mentioned:

flex file_name

gcc lex.yy.c

a.exe

You can run on Dev C++ by:

1. Save the .c and .h file
2. Compile the .c file
3. Run the .c file
4. Incase of issues in compiling and/or running, use the following command:

gcc filename.c -o filename
