C++ types

Exercise 0: Sizeof

Write a program to check the size of different data types: You can use the sizeof() operator

• char, bool, int, float, double, std::vector<double>, void*
• Write your own struct/class with different memembers with different types and check the size your datastructure
• Try to swap the member order, does anything change?

Exercise1: Alignment

Write a program to check the alignment of different data types: You can use the sizeof() operator

• char, bool, int, float, double, std::vector<double>, void*
• Write your own struct/class with different memembers with different types and check the size your datastructure
• Try to swap the member order, does anything change?

You can also use this code to easily inspect sizeof() and alignof(): code
