Transcribed Image Text:**Programming Exercise: Local Variable Declaration**
### Problem Statement:
10) Declare a local variable named `pwArray` that points to a 16-bit unsigned integer.
### Explanation:
To declare a local variable named `pwArray` that points to a 16-bit unsigned integer, you'll use pointers. In many programming languages like C or C++, this can be accomplished with the following syntax:
```c
uint16_t *pwArray;
```
Here, `uint16_t` is a standard type that represents a 16-bit unsigned integer, and the asterisk `*` indicates that `pwArray` is a pointer to this type. The variable `pwArray` can now be used to point to a location in memory that holds a 16-bit unsigned integer. Note that declaring the variable does not allocate space for the array itself, just the pointer.
### Detailed Steps:
1. **Type Specification**: `uint16_t` specifies a 16-bit unsigned integer.
2. **Pointer Declaration**: The `*` symbol indicates that `pwArray` is not a regular integer but a pointer to an integer.
3. **Variable Naming**: `pwArray` is the name given to the pointer that we will use to refer to the location in memory where our 16-bit unsigned integer(s) are stored.
This exercise helps in understanding the basics of pointers and memory management in lower-level programming languages.
