In this project, you'll be using your knowledge of variables, data types, and built-in methods to build a Mad Libs game!


In order to complete the story, you will have to prompt the user for certain words. We'll be gathering 7 values from the user in order to complete our story.
 
Take a look at lines 6 and 7 in **Madlibs.kt**. Line 6 prompts the user to enter their name and line 7 stores their answer in a variable called `name`.


Use a print statement to prompt the user to enter a friend's name. Below the prompt, store their answer in a variable called `friendsName`.

An adjective will be used to describe the nature of your trip!

Use a print statement to prompt the user to enter an adjective. Store the answer in a variable called `adjective`.

What city will you and your friend be driving to?!

Use a print statement to prompt the user to enter a city. Store the answer in a variable called `city`.

We need to know what band you and your friend will be driving to see!


Use a print statement to prompt the user to enter a band name. Store the answer in a variable called `bandName`.

For this story, you and your friend will be working for the summer to save money for your trip! You have already stored your friend's name in a variable called `friendsName`.

Using a string template, write print statement to prompt the user to enter what kind of job they and `friendsName` will do in order to save money. Store their answer in a variable called `work`.

Now, we need to figure out how many miles you and your friend will be traveling! Below the commented line declare a constant variable called `distance` of data type `Int`.

We will now prompt the user for an integer between 400 and 600 to represent the distance to be traveled, and store the value in `distance`. However, since `distance` is expecting a value of data type Int we must convert the value from `readLine()`, which is a String,  into an Int. 

There are a number of ways to do this, look into the [Kotlin Documentation](https://kotlinlang.org/docs/reference/) to find some built-in methods from Integer to convert a String into an Int. 

**Note:** See the **Hint** to see an example of storing user input as an Int.

Now that we know the cost of gas and the distance to be traveled, we need to calculate how much money you and your friend need for gas! 

The math to calculate the cost for gas is: `(cost of gas / mileage) * distance`.

Use the formula above and the variables created to find the total cost of gas and store it in a variable called `totalForGas`.

If we were to print the total cost for gas, it's likely to have an unnecessary amount of decimal places. 

In order to round down the value to 2 decimal points, we can use the following equation: 

`Math.round(totalForGas * 100) / 100.00`

Reassign the value of `totalForGas` to the result of that equation. 

**Note:** See the **Hint** to see the complete syntax.

You and your friend managed to save up more money than expected to cover all costs for your trip!

Create a new variable called `totalMoneySaved` and set it equal to `totalForGas` plus 200.  


We’re almost done with our program! Now let's work on our story. 

At the bottom of this program is a long `println()` statement containing our story. Note the words surrounded by parentheses `()`. The word placed in each pair of parentheses represents one of the variables we declared earlier in this program.

Go through this text and replace each pair of parentheses with the correct variable using a String template.

In order to run our program in this exercise we will follow these 3 steps:

1. Click the `Run` button when the code is complete

2. Use the following command in the terminal:
```
kotlinc Madlibs.kt -include-runtime -d Madlibs.jar
```

3. Follow up with the command:
```
java -jar Madlibs.jar
```



Great job completing this project. If you feel like challenging yourself, create your own "Mad Libs" story with new variables and prompts!
