The void pointer within C is a pointer that is not allied with any data types. This points to some data location within the storage means points to that address of variables. It is also known as a general-purpos
This blog covers all aspects of pointers in C. First, you’ll learn about the initialization and size of pointers. Afterward, we will discuss the types, use cases, advantages, and disadvantages of pointers in C. The concept of call by value and call by reference is also discussed in this...
There are different types of pointers in C: Null Pointer:A null pointer is a type of pointer which points to nothing. It generally points to the base address of the segment. In case of nothing is assigned to the pointer then it has a null value. It is generally used in header files ...
delete c++ achieves dynamic memory allocation using 2 keywords new(in c, it is called malloc) It allocates memory of n bytes in heap area and return address. Heap area is dynamic memory area, which is manage by c++ program. syntax :<pointer - variable – name >=new datatype[size]; si...
The C Dangling pointer is a type of pointer that actually points to a specific memory location that is to be free or deleted. There are some different ways where the pointer now acts as a dangling pointer. Most of the times there are only 3 different types/ways where the pointer will ac...
