Code for a Modified Calculator
How Can I Get This Code To:
a.) Put blank lines in between runs of the program to make the output file easier to read
b.) Use sentinel-controlled repetition (while statement) to allow the user to enter more than one set of integers for calculations and comparisons.
c.) Change the output to the file to be in the order and manner of the following:
The sum of integer1 and integer2 is sum. (Include input values in output.)
The difference between .... and .... is .....
The product of .... and .... is ....
The quotient of .... and .... is .... with a remainder of ....
OR: ***ERROR: Cannot divide by 0!
.... is larger (or greater) than .... OR The numbers are equal.
integer1 is even/odd (whichever it is)
integer2 is even/odd
