My question is how to fix the code so itworks without the bug.
int* foo) { int x = 7; return &x; } x is allocated on the stack when foo is called. When foo returns, the space allocated for x is deallocated. However, foo returns a pointer to this space which will be deallocated. As such, later attempts to dereference the returned pointer will likely clobber someone else’s memory. The returned result called a dangling pointer, since it points to a place in memory that it doesn’t actually own.
