Question 4

Time: 00:00:00

Ravi and Rupali are asked to write a program to sum the rows of 2X2 matrices stored in the array A.
Ravi writes the following code (Code A):
for n = 0 to 1
sumRow1[n] = A[n][1] + A[n][2]
end
Rupali writes the following code (Code B):
sumRow1[0] = A[0][1] + A[0][2]
sumRow1[1] = A[1][1] + A[1][2]
Comment upon these codes (Assume no loop unrolling done by compiler):

Code A will execute faster than Code B.

Code B will execute faster than Code A

Code A is logically incorrect.

Code B is logically incorrect.

The rule is DMOS 1.divide 2.multiply 3.operators 4.subtract a*b/c-d= 35/20(40)-10=60. a*b/(c-d)=35/10(40)=140 140-60=80

1st .............1400/20-10...........70-10..........60 2nd...........40*35/10.............1400/10......140 140-60=80

b will give only 45...because a & d are integer c=456-45=411
