How to Handle Pointer Dereferencing Errors in C

In C , dereferencing a null pointer does not raise an exception. Instead, it results in undefined behavior. This can be problematic, as it can lead to program crashes or unexpected results.

One approach to handling pointer dereferencing errors is to explicitly check for null pointers before dereferencing them. For instance:

<code class="c++">int* p = 0;
if (p != nullptr) {
    // Safe to dereference p
} else {
    // Handle null pointer error
}</code>

Another option is to use a specialized pointer type that performs null checks automatically. In recent versions of C , the std::optional type can be used for this purpose. For example:

<code class="c++">std::optional<int> p;
std::cout << *p; // Undefined behavior</code>
