· Program asks the user to type
a mathematical operator (a

. Program asks the user to type
the second number.
· Program works out the result
based on the chosen
mathematical operator.
. Program asks if the user wants to continue working with the previous result.
If yes, program loops to use the previous result as the first number and then repeats the calculation process.
If no, program asks the user for the fist number again and wipes all memory of previous calculations.
