I was just wondering how you could create a system memory leak using C++. I have done some googling on this but not much came up, I am aware that it is not really feasible to do it in C# as it is managed code but wondered if there was a simple way to do this with C++? I just thought it would be interesting to see how much the system suffers because of code not being written properly. Thanks.

Types of Memory Leaks Occurs when you free a block of memory that contains pointers to other memory blocks. Occurs when a function returns a pointer to an allocated block of memory, but the returned value is ignored in the calling routine.
Just forgetting to set a reference to null or more often forgetting to remove one object from a collection is enough to make a memory leak. Of course all sort of listeners (like UI listeners), caches, or any long-lived shared state tend to produce memory leak if not properly handled.
C # in TeluguThe memory leak occurs, when a piece of memory which was previously allocated by the programmer. Then it is not deallocated properly by programmer. That memory is no longer in use by the program. So that place is reserved for no reason.
Memory leakage occurs in C++ when programmers allocates memory by using new keyword and forgets to deallocate the memory by using delete() function or delete[] operator. One of the most memory leakage occurs in C++ by using wrong delete operator.
A memory leak occurs when you call new without calling a corresponding delete later. As illustrated in this sample code:
int main() { // OK int * p = new int; delete p; // Memory leak int * q = new int; // no delete } 
int main() {
while(true) new int;
}
