WebC++ Pointers. The C++ Pointer is a variable that is used to store the memory address as its value. However, to get the memory address of a variable, use the & operator. This means a variable has a unique memory location. This memory location has its own address. To access this address, we use the ampersand i.e., the & operator. WebTherefore it is must to check if a given index position exists in the array or not before accessing element at that index position. To check if index position is valid or not, first we need to fetch the size of the array, and then we can check, if the given index position is either greater than or equal to zero and less than the size of the array.
