PART 1:java style stack based calculator

Sources:

jcmain.cc jc.cc stack.cc

headers

jc.h stack.h

The jcmain.cc is the stack based calculator that supports the following operations: const,pop,store,load,add,sub,mul,div,p

Instructions to run and test the program:

1) Run make jc to compile and create the jc executable 2) Run the executable ./jc syntax:

opcode operand eg: To add two numbers: ./jc Enter a command(q to quit):const 10 Enter a command(q to quit):const 20 Enter a command(q to quit):add Enter a command(q to quit):p 30 Enter a command(q to quit):q

2)The program will quit if sufficient number of operands are not entered.

PART 2: java virtual machine

The jvm is the java virtual machine with support for conditional jump instructions

sources (in addition to those in part 1): jvmmain.cc jvm.cc jvm.h

Instructions to run and test the program:

1) Run make jvm to compile and create the executable jvm 2) Run the executable ./jvm syntax: ./jvm filename.jvm

PART 3:extended java virtual machine

The ejvm is the extended java virtual machine with support for subroutine calls.

sources (in addition to those in part 2): ejvm.h ejvm.cc ejvmmain.cc

Instructions to run and test the program:

1) Run make ejvm to compile and create the executable ejvm 2)Run the executable ejvm syntax: ./ejvm filename.jvm

Additional Notes:

1) To clean up all the output files, run make clean 2) Run make all to build all 3 parts at once
