Question
Chapter 10, Problem 17RQE
Program Plan Intro
Pointer:
Pointer will allow the user to indirectly access and manipulate the variable data contents. A pointer variable will hold the address of the data contents. If an asterisk “*” operator is present before the variable then that variable is referred as pointer variable. An asterisk “*” is also referred as indirection operator is used to dereferences the pointer.
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.
