A)
Address of (&) operator:
The main purpose of address operator “&” operator in pointers is to return the memory address of variables.
When the address of operator “&” is placed before the pointer variable, it will hold address of the pointer variable.
Example
//include necessary header
#include <iostream>
#include <string>
using namespace std;
//main method
int main()
{
//variable declaration
int a;
//display the address of the variable a
cout << &a;
}
Representing array using pointer notation:
- In general, array will have a continuous allocation of memory bytes, to represent the values present in the array it can be represented using its subscript value.
- So, to represent the values using pointer notation with an indirection operator the name of the array plus the subscript representing the value needs to be specified.
- When we represent only the array name, it will indicate the first element of the array.
- To represent the next element we need to increment the values by one to find the proceeding elements of the array.
- When “&” operator is used before an array it will return the address of the corresponding value.
