WebExample explained. Create a pointer variable with the name ptr, that points to a string variable, by using the asterisk sign * ( string* ptr ). Note that the type of the pointer has to match the type of the variable you're working with. Use the & operator to store the memory address of the variable called food, and assign it to the pointer.
WebAccess Array Elements. You can access elements of an array by indices. Suppose you declared an array mark as above. The first element is mark[0], the second element is mark[1] and so on. Declare an Array Few keynotes: Arrays have 0 as the first index, not 1. In this example, mark[0] is the first element. WebSyntax. In c++, if we want to declare an array of the pointer, then we have to create an array that will hold the address of the other elements, which point to some value for that address.
