Design a modular program that asks the user to enter the replacement cost of

a building and then displays the minimum amount of insurance he or she should buy for the property.

To design a modular program that calculates the minimum amount of insurance to buy for a building, you can break the program into several smaller functions. Here is a step-by-step explanation of how to design such a program:

1. Start by defining the modules or functions that the program will include. In this case, we will need at least two functions: one to get the replacement cost from the user and another to calculate the minimum insurance amount.

2. Create a function called `get_building_cost()` to prompt the user for the replacement cost of the building. This function should ask the user to enter the replacement cost and then return the value. Here's an example implementation in Python:

```
def get_building_cost():
cost = float(input("Enter the replacement cost of the building: "))
return cost
```

3. Create another function called `calculate_insurance_amount()` to calculate the minimum insurance amount based on the replacement cost. This function should take the replacement cost as a parameter, perform the necessary calculations, and return the minimum insurance amount. Here's an example implementation:

```
def calculate_insurance_amount(replacement_cost):
insurance_amount = replacement_cost * 0.8 # Assuming the insurance covers 80% of the replacement cost
return insurance_amount
```

4. Finally, write the main function that calls the other two functions and displays the result. Here's an example implementation:

```
def main():
replacement_cost = get_building_cost()
insurance_amount = calculate_insurance_amount(replacement_cost)
print("Minimum insurance amount to buy: $", insurance_amount)
```

5. Call the `main()` function to start the program execution.

The modular program will first prompt the user to enter the replacement cost of the building using the `get_building_cost()` function. Then, it will pass this value to the `calculate_insurance_amount()` function to calculate the minimum insurance amount. Finally, the program will display the result to the user.

You can customize this program based on the programming language you are using and any specific requirements or formulas for calculating the insurance amount.

To design a modular program that asks the user to enter the replacement cost of a building and then displays the minimum amount of insurance they should buy, you can follow these steps:

Step 1: Define a function to get the replacement cost from the user. This function will prompt the user for input and return the entered value as a numeric variable.

Step 2: Define a function to calculate the minimum insurance amount. This function will take the replacement cost as a parameter and calculate the insurance amount based on a predetermined percentage, such as 80% of the replacement cost. Return the calculated insurance amount.

Step 3: Call the first function to get the replacement cost from the user and assign it to a variable.

Step 4: Call the second function with the replacement cost variable as a parameter to calculate the minimum insurance amount.

Step 5: Display the calculated minimum insurance amount to the user.

Below is an example implementation in Python:

```python
def get_replacement_cost():
try:
replacement_cost = float(input("Enter the replacement cost of the building: "))
return replacement_cost
except ValueError:
print("Invalid input. Please enter a numeric value.")
return get_replacement_cost()

def calculate_minimum_insurance(replacement_cost):
return replacement_cost * 0.8 # Adjust the percentage as needed

replacement_cost = get_replacement_cost()
minimum_insurance = calculate_minimum_insurance(replacement_cost)

print("The minimum insurance amount should be: $", minimum_insurance)
```

This program prompts the user to enter the replacement cost of the building, validates the input, calculates the minimum insurance amount (80% of the replacement cost in this example), and displays the result. If the user enters an invalid input, it will prompt them again until a valid numeric value is entered.
