Q. 15 Consider the following code written in a pass-by reference language like FORTAN and these statements about the code.
subroutine swap(ix,iy)
it = ix
L1 : ix = iy
L2 : iy = it
end
ia = 3
ib = 8
call swap (ia, 1b+5)
print *, ia, ib
end
S1: The complier will generate code to allocate a temporary nameless cell, initialize it to 13, and pass the address of the cell to swap S2: On execution the code will generate a runtime error on line 1.1 S3: On execution the code will generate a runtime error on line 1.2 S4: The program will print 13 and 8 S5: The program will print 13 and-2
Exactly the following set of statement (s) is correct:
(A) S1 and S2
(B) S1 and S4
(C) S3
(D) S1 and S5
Answer: (B)
