Example: Using Function Pointers with unique_ptr

Consider a demonstration where a function pointer is utilized to specify a custom deleter:

#include #include // Function to act as a custom deleter void customDeleteFunction(int* p) { std::cout << "Deleting memory via function pointer
"; delete p; } int main() { // Construct unique_ptr with a function pointer as a custom deleter std::unique_ptr intPtr(new int(42), customDeleteFunction); // Use the intPtr... // intPtr goes out of scope, invoking customDeleteFunction return 0; }
