Question
Circulate the contents: Write the specification and construct an algorithm to circulate the contents of the variables A, B, and C as shown below: The arrows indicate that B gets the value of A, C gets the value of B and A gets the value of C.
Solution
Specification :
Circulated,B,C)
– – inputs: A,B,C all are real numbers
– – outputs: A,B,C, all are real numbers
T: = C
C: = B
B: = A
A: = T
Algorithm :
i) circulated,B,C)
ii) – – A,B,C
iii) T = C
iv) C = B
v) B = A
vi) A: = T
