Several issues including variables, operators, types

Hello, I'm using RetDec and found several issues regarding the decompiled code.
There are 9 programs with 10 issues, including integer recovery, operation values, operator recovery, assigning wrong values, and type recovery.

I've included the executables with source code, decompiled code, and compiler options in
[RetDec.zip](https://github.com/avast/retdec/files/15003567/RetDec.zip)

Hope you can take a look at them and let me know if I might be able to provide any help.

Start by examining RetDec.zip, which contains nine programs, their source code, decompiled code, and compiler options. Compare the reported integer recovery, operation and operator values, assignments, and type recovery across the examples; done would require addressing the ten discrepancies, though no specific source entry point or test is identified.
