Inheritance: OOP enables a new class to inherit properties and behaviors f...
A pointer is a variable that stores the memory address of another variable, enabling direct memory access and manipulation.
Pointers are used in languages like C and C++ to manage memory efficiently.
Example: int *ptr; // ptr is a pointer to an integer.
Pointers can be dereferenced to access the value at the memory address they point to.
Example: *ptr = 10; // assigns the value 10 to the integer pointed by ptr.
Pointer...
