stack to heap trend in languages

  •  C is mostly stack. I guess you seldom see malloc() and free() in business applications. I have seen a number of c applications but didn’t notice them. However, how does c pointers deal with automatic destruction of the objects they reference? I guess all such objects are declared and used in the same scope, never declared in an inner func and used in an outer func?
  • C++ biz apps use lots of new(), but by default, if you don’t call new() or malloc(), C++ uses the stack and global area. In terms of language support and encouragement, stack is still easier to use than heap in C++. I consider C++ as a transition between C and newer languages.
  • STL seems to be mostly heap, to support expansion
  • Java uses the heap more than the stack. Every object is on the heap. Memory leak becomes too likely so java had to provide garbage collector.
Conclusion: c -> c++ -> STL -> java, I see less stack and more heap usage.
