Write a simple calculator that operates as described here:

$1.$ The program starts by asking the user for two integers, which are stored in variables

having the type of int.

$2.$ Program asks whether the user wants to $1)$ add, $2)$ subtract, $3)$ multiply or $4)$ divide the

numbers.

$3.$ Next, the calculator will perform the desired operation and output the result.

$4.$ If the user tries to divide by zero, then the calculator gives an error message "Zero

cannot be used as a divisor." The result of the division operation must be rounded to

two decimal places.

Note: If the user does not select $1-4,$ the program prints the text "The operation was not

recognized."
