QUESTION 14:
Does the following program have a syntax error or a bug?
' Computing 23.8 plus 5.2 PRINT "The sum is", 23.8 * 5.2 END
No. The PRINT statement
PRINT "The square of 12 is", 12 * 0
is correct in syntax, but it does not calculate what it should. 12 * 0 means to multiply 12 by 0, which results in a zero, which is not what is wanted. This program has a bug.
The buggy program:
' Computing 12 times 12 PRINT "The square of 12 is", 12 * 0 END
. . . has a comment line that says what is wanted, and even has a string in the PRINT statement that said what the result should be. But the arithmetic is wrong, and a wrong number is printed.
