Dangling Pointers in C - Dangling pointers in C is used to describe the behavior of a pointer when its target (the variable it is pointing to) has been deallocated or is no longer accessible. In other words, a dangling pointer in C is a pointer that does
Pointers in C - C pointer is the derived data type that is used to store the address of another variable and can also be used to access and manipulate the variable's data stored at that location. The pointers are considered as derived data types.

When to use references vs pointers in C C - Reference variableReference variable is an alternate name of already existed variable. It cannot be changed to refer another variable and should be initialized at the time of declaration. It cannot be NULL. Th
(c) Finally access the value at the address available in the pointer variable. This is done by using unary operator * that returns the value of the variable located at the address specified by its operand. Following example makes use of these operations −...
A pointer in C is a variable that stores the address of another variable. Similarly, a variable that stores the address of a function is called a function pointer or a pointer to a function. Function pointers can be useful when you want to call a functio
Array of Pointers in C - Just like an integer array holds a collection of integer variables, an array of pointers would hold variables of pointer type. It means each variable in an array of pointers is a pointer that points to another address.
