What are wild pointers in C? Uninitialized pointers are known as wild pointers. The behavior of uninitialized pointers is undefined because they point to some arbitrary memory location. Wild pointers may cause a program to crash or behave badly. Note: Generally, compilers warn about the wild pointer. int *ptr; //ptr is wild pointer Let see […]

Both malloc and calloc are memory management functions which use to allocate the memory dynamically. In C language, calloc() gives

We use the const reference in C++ when we want to refer to a const type. It prevents changing the bounded object and also refers to a constant value (like 6, 27, 2.4 ..etc). In my previous article, I have explained the reference in detail if you had not read it, please check this link,

But C++ insist to use the reference but it is up to you and your requirement. Basically, reference defines an alternative name for an object

Constructors in C++ are special member functions that are automatically called when a class object is created. They are used to initialize the class objects. The constructor’s name is the same as the class name, and it does not have a return type. If you do not create your own constructor, then the compiler creates
