You are saying that the language is dynamically typed, it's not. That's because you cannot change the type of a variable during runtime, I guess it wouldn't work. In fact, this language has type deduction, but It's still statically typed.

Allowing user to write C code inside simC, this will be just copied and pasted into compiled C code without checking for syntax or compiling.

Describe the solution you'd like
Add two tokens BEGIN_C and END_C between which C code will be written, this should be directly pasted into appropriate location in compiled C code by simC compiler.

simC Code Example

MAIN
    var i = 0
    print(i)
    
    BEGIN_C
        int c = 10;
        int* ptr = &c;
        printf("%d\n", *ptr);
    END_C
END_MAIN

Explicit casting of types from by the user.

Describe the solution you'd like
Syntax will be similar to that of python (e.g. int(3.14159)). After successful type casting the type for the corresponding value should be updated in symbol table.

simC Code Example

MAIN
    var i = 3.14159
    var int_i = int(i)
    print(int_i)
END_MAIN

Implement sizeof operator to return the size of a variable.

Describe the solution you'd like
Whenever sizeof is called the type of the variable should be extracted from symbol table and based on this type return the size. Files to be changes for adding this are lexical_analyzer, parser, and compiler.

Note:- The size should not be static for every machine (e.g. size of an int variable should not return 4 for every machine), the result should be machine dependant and should be computed accordingly.

simC Code Example

MAIN
    var i = 3.14159
    var size = sizeof(i)
    print(size)
END_MAIN

Note: You can only start doing a question if it has been assigned to you by a maintainer. Once assigned to someone this questions will not be reassigned, it can only be reassigned if the person does not complete his/her task."

Describe the bug
Fails to take scope into account. Final value dicates the initial data type of the var even if they are contradictory in nature.

To Reproduce
simC code:-

var i = "asb"
MAIN
  var i = 10
  var j = 10
  print(i)
END_MAIN

C Code:-

#include <stdio.h>
int i = "asb";

int main() {
	int i = 10;
	int j = 10;
	printf("%d", i);

	return 0;
}

Expected behavior
C Code:-

#include <stdio.h>
char* i = "asb";

int main() {
	int i = 10;
	int j = 10;
	printf("%d", i);

	return 0;
}

Describe the bug
Cannot infer type of parameter inside function body. The type inference here should be done after calling but is being done in the definition itself.

To Reproduce
simC code:-

fun sum(a, b) {
  var c = a+b
  return c
}

MAIN
var d = sum(1,2)
END_MAIN

C Code:-
Not generated, throws error.

Expected behavior
C Code:-

int sum(int a, int b) {
  int c = a+b;
  return c;
}

int main() {
  int d = sum(1,2)

  return 0;
}

REAMDE goes inside readme-lang folder. The naming convention used is README-(language name).md where (language name) is the name of language in which README is being translated.

Note: Discuss with a maintainer in this thread before starting to translate the README.
