Question
Take input of the age of 3 people by user and determine oldest and youngest among them.
![**Objective:**
Take input of the age of 3 people by the user and determine the oldest and youngest among them.
---
This exercise aims to help students practice basic programming skills related to input handling and conditional statements. By the end of this task, students should be able to:
1. Take multiple inputs from the user.
2. Use conditional statements to compare values.
3. Determine and display the maximum and minimum values from the input.
### Step-by-Step Instructions:
1. **Basic Input Handling:**
- Prompt the user to enter the age of three different individuals.
- Store these ages in separate variables.
2. **Conditional Statements:**
- Use the `if`, `else`, and `elif` statements to compare the ages.
- Determine the oldest and youngest individuals based on the input.
3. **Output Results:**
- Display the age of the oldest and youngest individuals.
### Example Code (Python):
```python
# Prompting user to enter ages
age1 = int(input("Enter the age of the first person: "))
age2 = int(input("Enter the age of the second person: "))
age3 = int(input("Enter the age of the third person: "))
# Determining the oldest and youngest
oldest = max(age1, age2, age3)
youngest = min(age1, age2, age3)
# Displaying the results
print(f"The oldest person is {oldest} years old.")
print(f"The youngest person is {youngest} years old.")
```
### Understanding the Code:
1. **Input Collection:**
- `input("Enter the age of the first person: ")` prompts the user to enter an age which is then converted to an integer using `int()`.
2. **Finding Maximum and Minimum:**
- `max(age1, age2, age3)` compares the three ages and returns the largest value.
- `min(age1, age2, age3)` compares the three ages and returns the smallest value.
3. **Displaying Results:**
- The `print` function is used to output the oldest and youngest ages.
### Extensions:
To further enhance this exercise, students can:
- Validate the input to ensure ages are positive integers.
- Handle cases where two or more people might have the same age.
- Extend the code to accept ages from more than three individuals.
