Part 2/7:
Imagine you have a piece of code that correctly uses pointers and runs without any syntax errors, yet it still crashes. This may be due to mismanagement of object lifetimes and dangling pointers. For instance, consider a piece of code with a "use after free" vulnerability:
Dog* dog = new Dog();
delete dog;
// Later in the code
dog->speak(); // Crashes!
In this example, the pointer dog is deleted and later accessed again, causing the program to crash because it references memory that has already been freed. Understanding that syntax does not equate to correct usage is crucial in C and C++ programming.
