What is the difference between stack overflow and stack exchange?
5 Answers. Stack Exchange is a network of sites, of which Stack Overflow is one. They each use the same software but are generally geared towards certain topics… Stack Overflow being geared towards programming, and others being geared towards other particular topics.
What is stack overflow and underflow?
Stack Underflow & Overflow Stack underflow happens when we try to pop (remove) an item from the stack, when nothing is actually there to remove. Stack overflow happens when we try to push one more item onto our stack than it can actually hold.
What is stack overflow?
When a program attempts to use more space than is available on the call stack (that is, when it attempts to access memory beyond the call stack’s bounds, which is essentially a buffer overflow), the stack is said to overflow, typically resulting in a program crash. …
Why is Stackoverflow so toxic?
Misunderstanding the purpose of SO Stack Overflow has gained the reputation of being the place for answers to programming questions. As a result, people flock to SO in the hopes of getting an answer – expecting an answer, often needing an answer. They think that the purpose of SO is to answer their questions.
Which of the following is stack overflow condition?
Overflow condition: When stack is completely full (i.e. TOP= MaxSize -1 ) and we try to insert more element onto stack then this condition is called overflow condition and no further element could be inserted now until any element is deleted.
What happens when stack overflow occurs?
Usually, when a stack overflow error occurs, the program crashes and can either freeze or close the program. Any unsaved data or work is lost. The stack overflow error is often caused by an infinite loop or the creation of variables larger than the size of the call stack.
What is Stack Overflow with example?
A stack overflow is an undesirable condition in which a particular computer program tries to use more memory space than the call stack has available. When a stack overflow occurs as a result of a program’s excessive demand for memory space, that program (and sometimes the entire computer) may crash.
What is the purpose of Stack Overflow?
[Stack Overflow] is by programmers, for programmers, with the ultimate intent of collectively increasing the sum total of good programming knowledge in the world. No matter what programming language you use, or what operating system you call home.

What’s the difference between heap and stack based programming?
• Characteristics of stack-based and heap-based programming: • “Heap” is a “free store” that is memory space, when dynamic objects are allocated. • The heap is the memory space dynamically allocated new (), malloc (), and calloc () functions.
How are variables created in a stack overflow?
• Dynamically created variables (i.e declared variables) are created on heap before execution and stored in memory until the life cycle of object has completed. • Exploitation is performed • By corrupting data to override internal structures such as linked list pointers.
What does it mean to have a stack overflow?
A stack overflow is usually called by nesting function calls too deeply (especially easy when using recursion, i.e. a function that calls itself) or allocating a large amount of memory on the stack where using the heap would be more appropriate. Like you say, you need to show some code.
