Question

(C++) Given the following code,

for (int y 0; y 〈 4; y++) for (int z 0: z 〈 5; z++) cout << x * y * z くく endl;

please help me answer these three parts and please explain as simply as you can.

1.) How many iterations of the innermost loop? (please show calculation)

2.) What is the largest output?

3.) How many zeroes at the start? (please show/explain calculation)

Answer 1

ANSWER:-

total = 60

for first loop x=0 and second loop y=0 then third loop exicute total 5 times

again  for first loop x=0 and second loop y=1 then third loop exicute total 5 times

for first loop x=0 and second loop y=2 then third loop exicute total 5 times

for first loop x=0 and second loop y=3 then third loop exicute total 5 times

after x=0 total iteration 20 so same for x=1 and x=2

20+20+20=60

Question (2):- largest output = 24

Question (3):- 26  

for first loop x=0 and second loop y=0 then third loop exicute total 5 times and give 0

for first loop x=0 and second loop y=1 then third loop exicute total 5 times and give 0

for first loop x=0 and second loop y=2 then third loop exicute total 5 times and give 0

for first loop x=0 and second loop y=3 then third loop exicute total 5 times and give 0

so after exicution of x=0 total zero 20

for first loop x=1 and second loop y=0 then loop exicute total 5 times and give 0

for first loop x=1 and second loop y=1 then loop exicute total 5 times and give only first time 0 for z=0

so total 20+5+1=26
