Please help me on this coding problem :)

Answer:

a=4 , b=1

Explanation:

I'm not a computer science major at all but I think I can help you with this code.

Our program wants us to add 2 to a get new a value while also subtracting 1 from b value to obtain new b value. We we want to for for as long b is not 0 and a/b is nonnegative.

One round we get:

New a=0+2=2

New b=3-1=2

Let's see if we can go another round:

New a=2+2=4

New b=2-1=1

We can't go another round because b would be negative while a is positive which would make a/b negative. So our loop stops at this 2nd round.

a=4 , b=1

Other notes:

2nd choice makes no sense because a is always going to increase because of the addition on a and b was going to decrease because of the subtraction on it.

Third choice makes no sense because a/b doesn't even exist.

Fourth choice a/b is negative not nonnegative.

Convert the following numbers. (Please show all steps; no marks will be awarded if no steps are shown) [1.5 x 4 = 6 marks]

katen-ka-za [31]

Answer:

i. 10210212

ii. 100 101 001 in BASE 2

iii. 46.4631

iv. 12.453125

Explanation:

i. Converting to base 10 we get

= 10 x 162 + 13 x 161 + 9 x 160 = 2777

Converting to base 10 we get =

2777/3 = 925 with remainder 2

925/3 = 308 with remainder 1

308/3 = 102 with remainder 2

102/3 = 34 with remainder 0

34/3 = 11 with remainder 1

11/3 = 3 with remainder 2

3/3 = 1 with remainder 0

1/3 = 0 with remainder 1

Hence the Answer is 10210212

ii. = Octal is taken in pair of 3 bits , Writing binary of each number in 3 bits we get = 100 101 001 in BASE 2

iii. = 1 x 52 + 2 x 51 + 3 x 50 + 3 x 5-1 = 38.6 in decimal

Converting to Octal we get

38 /8 = 4 with remainder 6

4 /8 = 0 with remainder 4

.6 x 8 = 4.8

.8 x 8 = 6.4

46.4631

iv. = 1x 81 + 4 x 80 + 3 x 8-1 + 5 x 8-2 = 12.453125
