How to get the size of a type in C++?
c++, clang, oclint
Solution
In case you want 16 instead of 2 for `int16_t`
sizeof(my_var) * CHAR_BIT
`sizeof` give you how many bytes, and `CHAR_BIT` give you how many bits in a byte (normally 8)
Problem
I am looking for a C++ function that returns the size of a type. For example : ``` #include <stdint.h> int16_t my_var; int32_t size_of_var; // magical_function is what I'm looking for // size_of_var should be equal to 16 because my_var is a int16_t size_of_var = my_var.magical_function() ; ``` I know that size() exists to get the length of a string, so I guess there is a function indicating that too. Moreover, I'm working with Clang library, so I can get a Type (http://clang.llvm.org/doxygen/classclang_1_1Type.html) but I currently have no idea to compare 2 types and to know the bigger between those two.
