I don't know what the assignment operators lesson means. can anybody help me?

Answer 1

Assignment op is this : "="
The '=' asigns values to the variables.
ex:

int g;
g = 55;

In the lines above I've declared an integer variable and then I assigned 55 to it, with the = operator.

ps: The == , < and > are the comparison operators not the assignment op.

Answer 2

you mean those " <, >, <=, >=, =="?
its a way to compare 2 values.
for exemple:
3>2 = false

if you mean "+=, -= etc.."
its a "shortcut".
a+=b
wil work the same as
a=a+b
and the same with "-"
