Develop a menu-driven program that inputs two numbers and, at the user's option, finds their sum, difference, product, or quotient.
Do you need help with the flow-chart, algorithm, the coding or debugging?
It would be best for you to tell us what you have learned, and what you have done so far.
To develop a menu-driven program that performs calculations on two numbers, you can follow these steps:
1. Display a menu of options for the user to choose from. For this program, the options are sum, difference, product, and quotient.
2. Prompt the user to enter two numbers.
3. Based on the user's choice, perform the corresponding calculation (sum, difference, product, or quotient) on the two numbers.
4. Display the result of the calculation to the user.
Here's an example of how you can implement this in Python:
```python
def calculate_sum(a, b):
return a + b
def calculate_difference(a, b):
return a - b
def calculate_product(a, b):
return a * b
def calculate_quotient(a, b):
# Check if the second number is zero to avoid division by zero error
if b == 0:
return "Cannot divide by zero"
return a / b
def menu():
print("Menu:")
print("1. Sum")
print("2. Difference")
print("3. Product")
print("4. Quotient")
choice = input("Enter your choice (1-4): ")
if choice in ['1', '2', '3', '4']:
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))
if choice == '1':
result = calculate_sum(num1, num2)
print(f"The sum is: {result}")
elif choice == '2':
result = calculate_difference(num1, num2)
print(f"The difference is: {result}")
elif choice == '3':
result = calculate_product(num1, num2)
print(f"The product is: {result}")
elif choice == '4':
result = calculate_quotient(num1, num2)
print(f"The quotient is: {result}")
else:
print("Invalid choice. Please enter a number from 1 to 4.")
# Run the menu function to start the program
menu()
```
This program will display the menu options, prompt the user for their choice, and perform the corresponding calculation based on the selected option. The result will then be displayed to the user.
