Such a variable is called apointer variable(for reasons which hopefully will become clearer a little later). In C when we define a pointer variable we do so by preceding its name with an asterisk. In C we also give our pointer a type which, in this case, refers to the type of data ...
A dangling pointer arises when you use the address of an object afterits lifetime is over. This may occur in situations like returningaddresses of the automatic variablesfrom a function or using theaddress of the memory block after it is freed. The followingcode snippet shows this: class ...

Pointers provide a way to manipulate data directly in memory, leading to efficient and powerful programming techniques. Definition and Usage A pointer in C is declared by specifying a data type followed by an asterisk (*) before the variable name. The data type indicates the type of data the...
