What is stack overflow profile?
Stack Overflow is a question and answer site for professional and enthusiast programmers. It features questions and answers on a wide range of topics in computer programming. It was created to be a more open alternative to earlier question and answer sites such as Experts-Exchange.
How did stack overflow start?
Jeff started working on the code in April 2008, recruited two other programmers to join him (Geoff and Jarrod, who are still here), and the three of them heroically launched what became Stack Overflow in September 2008. And thus began the Stack Overflow Age.
How much does stack overflow cost?
Stack Overflow for Teams costs $10 per month for up to 10 users, with each additional user costing $5 per month (or $50 per year). For reference, Stack Overflow Enterprise costs around $200 per user per year, although the use case there is different.
How long does it take to get a response on stack overflow?
1 Answer. The average is 3.71 daysbut the standard deviation is 25.2 days. It number is so high because there are some questions like Date arithmetic in Unix shell scripts that take over 2 years to get the answer, creating a strong bias towards a long time.
What is stack overflow for teams?
Stack Overflow for Teams is a private, secure Q&A platform that mimics the way people naturally think about, share, and find information. When it comes to knowledge management, you don’t need more information, you need the right information. We offer a plan for companies of every size.

Can I use stack overflow code?

How does stack overflow make money?
Stack Overflow aims to provide value by matching developer skills to a company’s specific requirements, and improve the hiring process. Another source of revenue is their Ads solution. This includes house ads (ads for the sites on the network) and community ads (voted on by the community).
What causes stack overflow?
The most-common cause of stack overflow is excessively deep or infinite recursion, in which a function calls itself so many times that the space needed to store the variables and information associated with each call is more than can fit on the stack.
What happens if stack overflows?
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.
How can stack overflow be prevented?
Avoid or strictly limit recursion. Don’t break your programs up too far into smaller and smaller functions – even without counting local variables each function call consumes as much as 64 bytes on the stack (32 bit processor, saving half the CPU registers, flags, etc)
How do I know if I have stack overflow?
A method of detecting stack overflows is to create a canary space at the end of each task. This space is filled with some known data. If this data is ever modified, then the application has written past the end of the stack.
What happens if heap memory is full?
Your heap will get full. When this happens, malloc() won’t be able to allocate memory anymore and it’s going to return NULL pointers indefinitely. Your heap will get full. But here, your program will exit, since you’re breaking out of the while loop in case malloc() fails to allocate memory.
What is a heap overflow attack?
A heap overflow or heap overrun is a type of buffer overflow that occurs in the heap data area. When this happens, the buffer that is assumed to be freed will be expected to hold two pointers FD and BK in the first 8 bytes of the formerly allocated buffer. BK gets written into FD and can be used to overwrite a pointer.
What is buffer overflow with details?
A buffer overflow (or buffer overrun) occurs when the volume of data exceeds the storage capacity of the memory buffer. As a result, the program attempting to write the data to the buffer overwrites adjacent memory locations.
How many types of buffer overflow attack are there?
Do strongly typed languages suffer from buffer overflow?
Languages that are strongly typed and do not allow direct memory access, such as COBOL, Java, Python, and others, prevent buffer overflow from occurring in most cases. Nearly every interpreted language will protect against buffer overflows, signaling a well-defined error condition.
Why is buffer overflow dangerous?
Buffer Overflow and Web Applications Attackers use buffer overflows to corrupt the execution stack of a web application. By sending carefully crafted input to a web application, an attacker can cause the web application to execute arbitrary code – effectively taking over the machine.
