C++ is a well-known programming language which focuses on effective hardware utilization. C++ compilers are able to generate efficient executable code that takes advantage of the hardware elements. C++ supports the object-oriented paradigm and therefore it provides classes and structs. Compilers are enabled to add extra padding and alignment bytes between the members of a class. This option may result in different size of a class based on the different order of the class and contradicts the optimal memory consumption demand. In this paper, we propose an approach for optimizing memory utilization. This approach includes a static analysis tool that examines the classes and reports if the order of members is sub- optimal regarding memory consumption. We analyze open source projects and realize every observed project contains such a subtle problem.
