= *Inspecting the Virtual Table for Inheritance (C++)*
|
||||||
|
|
||||||
|
In C++, To inspect whether a pointer to a allocated object is of type
|
||||||
|
the pointer is declared to a particular class or it is object of a class
|
||||||
|
which is dervied from the class of which the type of the pointer is.
|
||||||
|
|
||||||
|
To check it, we can use the virtualy pointer table of derived class
|
||||||
|
which can help us in such information.
|
||||||
|
|
||||||
|
We can use command:
|
||||||
|

=== *GDB Command Debug Levels*
|
||||||
|
|
||||||
|
There are different level of debugging information that we can achieve
|
||||||
|
using the different type of `-g` flag during compilation.
|
||||||
|
|
||||||
|
This is mainly to get _macro_ information as these are not added to
|
||||||
|
debug symbol by default.
|
||||||
|
|
||||||
|
|
||||||
|
Different levels of Debugging symbols:
|
||||||
|
|
||||||
|
1. -g0
|
||||||
|
2. -g1
|
||||||
|
3. -g2 (default)
|
||||||
|
4. -g3
|
||||||
|
5. -ggdb3 (highest level specifically for GDB debugger)
|
||||||
|
|
||||||
|
To see the information for all the macro, use command:
|
||||||
|

= *Static Analysis tools*
|
||||||
|
|
||||||
|
We can use cppcheck, which is static analysis tool.
|
||||||
|
Or we can use `-Weffc++` flag with `g++` for static analysis.
