I don't understand this loops thing

Answer 1

+=
-=
*=
/=
%=

Are shorthands for x = x + x

x = 0;

x += 5 means x = x + 5; result: 5
x -= 5 means x = x - 5; result: -5
x *= 5 means x = x * 5; result 0

Etc

In your case, x+= 2 means
x = x + 2

Answer 2

Which part exactly?

Answer 3

while loops repeat the code inside their bodies until their condition fails. Meaning that the thing inside their brackets becomes false. In most languages, 0 evaluates to false and all other numbers to true.
Is there any specific sample in the tutorial that confused you perhaps?

Answer 4

Everything about the while loops

Answer 5

i = 1
while i <=5:
print(i)
i = i + 1

print("Finished!")

Why does it print
1
2
3
4
5
Finished!

Answer 6

While will repeat the code as long as the condition is true

Today is sunny, while its sunny, go outside

If it starts raining, get back inside

bool weather = sunny;

While (sunny)
{ go outside }

You also need a condition so you're not stuck in endless sunny days - it's usually sunny for 5 days sooo

int days = 0;

while (sunny && days <5 )
{ go outside
days++ (this will add a new day after the code runs)
}

On the fourth day, variable "days" will hit 5 and you will go back inside

Answer 7

Loop executes 5 times and runs the print command

After its done looping, it prints out finish
