# Write a program that will add, subtract, multiply or divide two numbers.
# Numbers and the operation sign are entered by the user. After the calculation is complete, the program should not end,
# and should request new data for calculations.
# Program termination should be performed when the character '0' is entered as an operation sign.
# If the user enters an incorrect character (not '0', '+', '-', '*', '/'), then the program should inform him of the error and
# request the operation sign again.
# Also inform the user about the impossibility of dividing by zero if he entered 0 as a divisor.
