Question-54
Determine which characteristics of an algorithm described in the text (after Algorithm 1) the following procedures have and which they lack. Select characteristics that the procedures have and leave characteristics unselected that the procedures lack.
a) procedure double (n : positive integer
while n > 0
n – 10n
b) procedure divide ( n : positive integer)
while n 
0
m = 
n = n – 1
c) procedure sum ( n : positive interger)
sum = 0
while i < 7
sum = sum + i
d) procedure chose ( a , b : integers)
x = either a or b
