Short answer needed

Question

Can somebody explain to me what "++", "--", "==, means? In simple language cuz I'm rookie.. thanks

Answer 1

++ increment
i++ --> i = i + 1
-- decrement
i-- --> i = i - 1
== boolean operator (equal)
2 == 4 --> false
2 == 2 --> true

Answer 2

"i++" - post-increment,
"i--" - post-decrement: "returns the original value before changing the variable."

"++i" - pre-increment,
"--i" - pre-decrement: "first changes the variable, and then returns the value".

Answer 3

i=5;
i++;
print(i); //prints 6;

i=5;
i--;
print(i); //prints 4;

== is for comparing variables.
for example:
a=5;
if (a==5) print("Hello");
//prints Hello

Answer 4
