When dealing with complex object-oriented binaries or C structs: Open the ( Shift + F9 ). Press Insert to define a new struct and map out its fields.
Open your binary and let IDA complete its initial auto-analysis. Navigate to the (typically on the left side) and double-click the function you wish to analyze. This will center your view on that function in the IDA View-A assembly window. Step 2: Trigger the Decompiler

Reversing C++ programs with IDA pro and Hex-rays - Aris' Blog
if ( !strcmp(input, "secret") ) return 1; else return 0; When dealing with complex object-oriented binaries or C
IDA periodically reanalyzes code. If you rename a variable and it reverts, it’s likely because IDA’s data flow analysis changed the variable’s scope.
This article will serve as your complete guide. We will cover the technical mechanics of decompilation, step-by-step workflows, the strengths and pitfalls of the generated C code, and advanced techniques to reverse even the most stubborn binaries. Navigate to the (typically on the left side)
Right-click function names and choose "Set item type" ( Y ) to define parameters and return types. Use Comments: Press / to add comments to explain the code. IDA Pro Decompiler Limitations While powerful, the Hex-Rays decompiler has limitations:
Comments, variable names, and some types are lost during compilation.
Mastering these keyboard shortcuts will significantly speed up your reverse engineering workflow in the Pseudocode view:
