Question

write a computer solution that accepts as input an integer value and then output the sum of the digits int he number as well as the number of digits it has with appropriate captions

Answer 1

inputs the integer, trapping for overflow
stores it in variable longIntNum

longTempNum = longIntNum


powerOf10 = 1
numDigits = 0

While longIntNum > powerOf10
powerOf10 = powerOf10 * 10
numDigits = numDigits + 1
End While

SumOfDigits = 0
powerOf10 = powerOf10 / 10

While powerOf10 >= 1
digit = longTempNum \ powerOf10 <---- strict integer division here; NO ROUNDING. EX. 123 / 100 = 1.
sumOfDigits = sumOfDigits + digit
longTempNum = longTempNum Mod powerOf10
powerOf10 = powerOf10 / 10
End While

output numDigits
output sumOfDigits
