Question

Describe a situation in which you would want to use integer division in a program. Then, write the line of code that would use integer division.
Describe a situation in which you would want to use modulus division in a program. Then, write the line of code that would use modulus division.
A customer has hired you to code a cooking mystery game. Here is part of the narrative: “When the player enters the kitchen, they can choose to preheat the oven or chop vegetables. If they choose to preheat the oven, they will get a message that the oven is broken. If they choose to chop the vegetables, they will get a message that the knife is missing.” Write the code for this situation.
Write three lines of code using a sequence (no iteration or selection) that would be appropriate for a story or game.
Will the output for each of these print statements be the same? Explain your answer.
num1 = 10
num2 = 50
num3 = 10
num4 = 0

print((num1 + num2) * (num3 + num4))
print(num1 + num2 * num3 + num4)

Answer 1

### Integer Division Scenario
**Situation**: Suppose you are designing a program that calculates the number of full boxes needed to pack a certain number of items. Each box can hold a fixed number of items, and you want to know how many complete boxes you will need.

**Line of code**:
```python
items = 25
box_capacity = 7
full_boxes = items // box_capacity
```

### Modulus Division Scenario
**Situation**: In the same packing program, you may also want to determine how many items will be left unpacked after filling the boxes. Modulus division can help identify the remainder.

**Line of code**:
```python
remaining_items = items % box_capacity
```

### Cooking Mystery Game Code
The player can either preheat the oven or chop vegetables. Based on their choice, they will receive a specific message.

**Code**:
```python
choice = input("Enter 'preheat' to preheat the oven or 'chop' to chop vegetables: ")

if choice == 'preheat':
print("The oven is broken.")
elif choice == 'chop':
print("The knife is missing.")
```

### Sequence of Code Lines for a Story or Game
Here are three lines of code that could be used in a story or game context:

```python
print("You enter the dark room and hear a strange noise.")
print("Suddenly, you see a shadow move across the wall.")
print("Your heart races as you prepare to confront whatever lurks in the corners.")
```

### Output Explanation
For the following print statements:
```python
print((num1 + num2) * (num3 + num4))
print(num1 + num2 * num3 + num4)
```
**Will the output be the same?**

**Explanation**: No, the output for these two print statements will not be the same due to operator precedence in Python.

1. The first statement `print((num1 + num2) * (num3 + num4))` computes the addition inside the parentheses first:
- `(10 + 50)` gives `60`
- `(10 + 0)` gives `10`
- Then it multiplies `60 * 10` which equals `600`.

2. The second statement `print(num1 + num2 * num3 + num4)` computes based on operator precedence (multiplication first):
- `num2 * num3` is calculated first: `50 * 10` gives `500`.
- Then it computes `10 + 500 + 0`, which equals `510`.

So, the first statement will output `600`, and the second will output `510`, thus they will not be the same.
