Yes, but you won't know their names, such as printf(), etc.
In a lot of C++ code, standard library implementations are heavily dependent upon templates, and a good optimizing compiler will do away with traditional function calls where it can, opting to inline things instead. As a result, the boundary between "subroutines" being called gets extremely blurry, to the point of being nearly undetectable, unless you have a great deal of experience with reverse engineering machine code.
