Question

Answer 1

Sure Here are a few tips to help you get started.

-Start by identifying the basic operations you want your calculator to perform, such as addition, subtraction, multiplication, and division.

-Next, think about how you will take input from the user. One approach is to have the user enter the numbers and the operation they want to perform (e.g. "2 + 3") as a single string, and then parse that string to extract the numbers and operation.

-Create variables to store the numbers and the operation the user has entered.

-Write a function that takes the two numbers and the operation as arguments and returns the result of the calculation.

-Use a loop to continuously prompt the user for input and output the result of the calculation until the user decides to exit the program.

-Consider adding error handling to your code, so that the calculator can handle invalid input or operations gracefully

Answer 2

Prompt the user to enter

1- number
2- Operator
3- number

Then evaluate and validate the operator sign using if else statement to print the result or an error.

Hint: user input return string type.
