Answer to the following iterations are:

a)

In the following for-loop, the loop will starts from 0 and end at 9.

for example:

0 1 2 3 4 5 6 7 8 9

So, the loop will iterate 0-9, which means 10 times.

b)

In the following for-loop, the loop will starts from 0 and end at 8 but in the gap of 2 because of the increment of 2 in the variable "i".

for example:

0 2 4 6 8

So, the loop will iterate even times or 5 times, which means 0 2 4 6 8.

c)

In the following for-loop, the loop will starts from 0 and end at 9 but in the gap of 3 because of the increment of 3 in the variable "i" and the value is assign in the variable "incr" is 3.

for example:

0 3 6 9

So, the loop will iterate 4 times, which means 0 3 6 9.

d)

In the following for-loop, the loop will starts from 3 and end at 9 but in the gap of 3 because of the increment of 3 in the variable "i" and the value is assign in the variable "incr" is 3.

for example:

3 6 9

So, the loop will iterate 3 times, which means 3 6 9.

e)

In the following for-loop, the loop will starts from 10 and end at 1 which means reverse order.

for example:

10 9 8 7 6 5 4 3 2 1

So, the loop will iterate 10-1, which means 10 times in reverse order.

f)

In the following for-loop, the loop will not works because of the condition which is i is less than 0 but in the following code loop will starts from 3.

So, that's why loop will not iterate.

g)

In the following for-loop, the loop will starts from 1 and end at 9 but in the multiple of 3 because the variable "i" will multiply by the variable "incr" and the value is assign in the variable "incr" is 3.

for example:

1 3 9

So, the loop will iterate 3 times, which means 1 3 9.

h)

In the following for-loop, the loop is the infinite loop because of the condition which is i is less than max but and the loop will starts from 0 and goes on infinite times.

So, that's why it is the infinite loop.
