A variable provides us with named storage that our programs can manipulate. Each variable in C++ has a specific type, which determines the size and layout of the variable’s memory; the range of values that can be stored within that memory; and the set of operations that can be applied to the variable. The name…

Applications of Pointers in C
One of the most important features of C is that it provides low-level memory access with the concept of pointers. A pointer is a variable that stores the address of another variable in the memory. The provision of pointers has many applications such as passing arrays and struct type to a function and dynamic memory allocation, etc.…
