' Cost of electricity ' PRINT "Enter number of kilowatt-hours" INPUT KWH PRINT "Enter dollars per kilowatt-hour" INPUT RATE PRINT "Cost in dollars:", KWH * RATE END
A program executes statements one
at a time in sequence.
If an INPUT
statement is waiting for
you to type a number, no other
statement will execute until this has happened.
Say that the above program is running, and that you have correctly typed in the first number but have incorrectly typed in the second number, as below:
Enter number of kilowatt-hours ? 1294 Enter dollars per kilowatt-hour ? $0.096480 Redo from start ? _
The second number is incorrect because the "$" can not be part of a number.
What should the user type now so that the program will continue?
