Write a algorithm to print all even numbers in descending order?

AnswerIf A=10, B=2...

Then the algoritm is :-

STEP1 : START.

STEP2 : A=10.

STEP3 : B=02.

STEP4 : C=A-B.

STEP5 : PRINT C.

STEP6 : STOP.

AnswerYou cannot print every even number in descending order, because there is no greatest even number. Or you want something like this:

infinity

infinity-2

infinity-4

Answerstep 1: start

step 2: Input N

step 3: If N<=1, go to step 5

step 4: if N%2=0, Print N

N=N-1, go to step 3

step 5: End
