• variables of double, float, char, unsigned, and pointer types
• the typedef keyword
• the sizeof(...) function (which takes either a type or a variable)
• change the operations from slt to sltu for example for unsigned
• fix globals (about 11 cases)

Keep this issue open and drop in any comments on project management / time distribution

• add structs to symbol table
• declaration and use of structs

If statements
Int variables
while loops
arithmetic expressions
logical expressions
local variables

• arrays declared globally (i.e. outside of any function in your file)
• int a[x];
• int a[x] = {1, 2, 3 .... x}
• int a[x] = {1}
• int a[x] = {1,2}
• multidimensional arrays?
• arrays declared locally (i.e. inside a function
• reading and writing elements of an array
• support expression indexing :/

• character literals, including escape sequences like \n
• strings (as NULL-terminated character arrays)
• finalize implementation with STO
• fix for pointers

• function definition
• return statement
• functions that take up to four parameters
• files containing multiple functions that call each other (requires symbol table)
• recursive function calls

• taking the address of a variable using the & operator
• dereferencing a pointer-variable using the * operator
• Pointer arithmetic
• Pointer indexing
• Check GCC policy for char pointers / arrays (is it by bytes or buy words)
• Multi-depth pointers
• float / double arrays

Setup ANTLR for C++ with a basic grammar and tree-traversal:

• Configure ANTLR with C++
• Implement a basic grammar
• Traverse the AST and output basic translation

• Traverse AST
• Generate Python

Enhanced testing for the translator:

• Make sure all tests pass
• Add edge cases tests
• Use other people's tests

• implement unary (-4 is assigned as 4, etc...)
• debug z= x<=y;
• implement ++ and --
• one line conditional (cond ? true_exec : false_exec)
• local variables: add symbol table extension for compoundStatement (aka {list})
• debug function call failures (0 param + mutual recursion)

• C necessary grammar fro the translation
• Translate C instructions to Python

Translation requirements:

• Local variables
• Global variables
• Functions
• Main function
• If
• IfElse
• While
• Return
• Sequences
• Assignment
• Operators
• Functions Invocations

• Create the symbol table objects (enum, variable, array, function)
• Implement the objects
• Implement global declarations for integers

• 25%
• 50%
• 75%
• 100%

• Make compiler runnable as per requirement
• Run on the given tests
• Verify stack pointer operation

• switch statements
• for loops
• the break and continue keywords
• switch: skip the pre-case scope
• for: all combinations of emptiness
• the enum keyword
