1 Assignment Repetitin CSC Spring 07 P7-79 Questin all a. True- a fr statement is very cnvenient when yu knw hw many times yu will execute the lp in advance (in actuality I d never ask this questin) b. True Any f the iterative statements is pwerful enugh t simulate the thers c. True d. False if the cnditin is false the first time thrugh it wn t execute. e. False yu can nest lps within lps f. True g. True h. False basically unlimited except by available memry i. True. i gets decremented and then incremented. It will always be. j. False It never executes since the initial cnditin is false Questin a, c, e a. -0 explanatin. Shrt has greatest negative value f -78, 4000 is beynd that number. S since we are wrapping arund (due t tw s cmplement), -78+ is casts up 4000 casts up c

3 Questin a, b a. duble sum = 0.0, savings_per_day =.0 int days=0, i=; while (i <= 0) { sum = sum + savings_per_day; savings_per_day = *savings_per_day; i++; } b. duble sum = 0.0, savings_per_day =.0 int days=0; while (sum < ) { sum = sum + savings_per_day; savings_per_day = *savings_per_day; days = days+; } Questin 8 b,d b. This is an infinite lp; i starts at 0 and increases, s the lp never ends since it keeps ging as lng as i > d. The real prblem is that if -999 is entered as an even entry the lp desn t end Aside frm nt declaring and initializing sum and nt asking fr entry f numbers, the real prblem is that every ther input number is the test, s if -999 is entered nd, furth, etc, it is nt a sentinel, but is just added.
