How to create a function in IDA Pro?
IDA almost give you ability of doing anything wih obfuscated code to help you to understand code correctly. Addendum After converting to C (code), do Alt+P to create/edit function.
How is the type information used in Ida?
IDA will use the type information to comment the disassembly with the information about function arguments. It can also be used by the Hex-Rays decompiler plugin for better decompilation. Here is an example of a function declaration: To delete a type declaration, please enter an empty string.

How does Ida parse an executable file for analysis?
During that time, IDA will also load and parse the actual code instructions of the executable file into the assembly instructions of the selected processor module. Those assembly instructions are then also showed to the user for analysis.
How can I see if Ida is processing a file?
Go with default options and you will see IDA is processing the file, you can start the analysis now. One of the most important thing is to look on the Import and Export function tabs to get a compact view that how many and what api is our target application using.
How many files are there in IDA Pro?
Upon opening a new file to analyze with IDA Pro, it analyzes the whole executable file and creates an.idb database archive. The .idb archive contains four files [1]:
