What and where are the stack and heap?
2008年9月17日 · Stored in computer RAM just like the stack. In C++, variables on the heap must be destroyed manually and never fall out of scope. The data is freed with delete, delete[], or free. Slower to allocate in comparison to variables on the stack. Used on demand to allocate a block of data for use by the program.
c++ - what's the difference between callstack and stack? - Stack …
2021年2月5日 · @NikaKurashvili The stack section in memory is where the function calls are stored. However, a call stack is an actual stack of actual calls. So, if you call f1, then you have a small stack of a single item stored in the stack section of memory. When f1 calls f2, then the call stack in question increases from 1 function to two functions. And so on.

c++ - Trying to access an index of an std::stack - Stack Overflow
2012年11月17日 · Actually in your case container choice is wrong. If you need to access elements randomly (not only top stack element) use std::vector instead. Corresponding operations will be push_back() to place element on stack top, pop_back() to extract element from stack top and back() to access top stack element.

c++ - How can I print out the contents of std::stack and return its ...
2013年7月29日 · First: The size of a stack is given by std::stack.size(). Then, in modern C++ the STL with algorithms is used more and more. So the following solution makes use of that. The precondition is that a stack uses contiguous memory. That is guaranteed at the moment. Output is done via a one liner. See the following example:
c++ - What is stack unwinding? - Stack Overflow
2010年2月25日 · In a general sense, a stack "unwind" is pretty much synonymous with the end of a function call and the subsequent popping of the stack. However, specifically in the case of C++, stack unwinding has to do with how C++ calls the destructors for the objects allocated since the started of any code block.
c++ - How is Stack implemented in STL? - Stack Overflow
2016年3月11日 · stack is an adapter which uses another container for the underlying storage, and links the functions push, pop, emplace etc. to the relevant functions in the underlying container. By default, std::stack uses std::deque as underlying container. But you can specify your own, e.g. std::stack<T, std::vector<T>> s;.
What are stacks used for? Why are they in C++? - Stack Overflow
2011年12月20日 · In C++, std::stack<> is a class template whose data can be any type. There are many situations where last in, first out is exactly what you need. An example are virtual machines or interpreters that utilise a stack architecture to save the running state during execution of functions/procedures.
