Question
### Execution of Loops and Variable Values in MSP430 Code Segment

**Problem Statement:**

Answer the following questions regarding the execution of loops. Assume that the code below is executed on an MSP430 (i.e., an `int` has a size of two bytes).

#### Question:

a. In the following code segment, how many times does the loop iterate? What are the values of `kk`, `mm`, and `inVal` at the end of the first and last loops? (You can specify the values in either hex or decimal, whichever you prefer.)

#### Code Segment:

```c
unsigned int inVal, out, kk = 0x0001, mm = 0x1000;
char count = 1;

// ...
while(kk != 0)
{
    inVal = (mm + kk) / kk;

    // ...

    mm /= 2;
    kk = kk << 1;
}

// ...
```

### Explanation:

#### Loop Analysis:

- **Initial Values:**
  - `kk = 0x0001` (in hexadecimal), which is 1 in decimal.
  - `mm = 0x1000` (in hexadecimal), which is 4096 in decimal.
  - `inVal` is an uninitialized unsigned integer.
  - `count = 1` (in decimal).

- **Condition:**
  - The while loop executes as long as `kk` is not equal to 0.

- **Body of Loop:**
  1. Calculate `inVal` as `(mm + kk) / kk`.
  2. Divide `mm` by 2.
  3. Left shift `kk` by 1 (equivalent to multiplying `kk` by 2).

#### Step-by-Step Iteration:

1. **First Iteration:**
   - `kk = 1`
   - `mm = 4096`
   - `inVal = (4096 + 1) / 1 = 4097`
   - `mm = 4096 / 2 = 2048`
   - `kk = 1 << 1 = 2`

2. **Second Iteration:**
   - `kk = 2`
   - `mm = 2048`
   - `inVal = (2048 + 2) / 2 = 1025`
   - `mm = 2048 /
