C++ programs can be defined as a collection of objects that interact with each other by calling their methods. Objects Objects have states and behaviors. For example: a dog’s state – color, name, breed; behavior – wagging, barking, eating. Objects are instances of classes. Classes Classes can be defined as templates/blueprints that describe the behaviors/states … Read more

So far, we have learned about the two types of variables supported by C++: Ordinary variables are variables that hold values of a certain type. For example, creating an integer variable means that the variable can hold integer values. Pointers are variables that store the address of another variable. You can retrieve the value pointed … Read more
As we know, pointers are used to point to variables; similarly, function pointers are used to point to functions. They are primarily used to store the address of a function. We can use function pointers to call functions or pass function pointers as parameters to another function. Function pointers are mainly useful in scenarios such … Read more
