Sure, here is a step by step solution in Python:

Step 1: First, we need to take an integer input from the user. We can use the `input()` function for this. Since `input()` function returns a string, we need to convert it into an integer using the `int()` function.

```python
a = int(input("Enter a number: "))
```

Step 2: Now, we need to perform the unary operations on the variable `a`. In Python, `++a` and `--a` don't actually exist as they do in some other languages like C++. In Python, `++a` or `--a` will not increment or decrement the value of `a`. They will just return the value of `a`. So, `a = ++a * --a` will be equivalent to `a = a * a`.

```python
a = a * a
```

Step 3: Finally, we need to display the final value of `a`. We can use the `print()` function for this.

```python
print("The final value of a is", a)
```

So, the complete program will be:

```python
a = int(input("Enter a number: "))
a = a * a
print("The final value of a is", a)
```

This program will take an integer as input, perform the unary operations, and then display the final value.
