NASL2 imported some nice operators from C:

`++`is the pre-incrementation (++x) or post-incrementation (x++).`++x`adds 1 to**x**and returns the result;`x++`adds 1 to x but returns the previous value.`-`is the pre-decrementation (-x) or post-decrementation (x-).`+=`have the same meaning as in C`-=``*=``/=``%=`

e.g.`x += y;`is equivalent to x = x + y;but**x**is evaluated only once. This is important in expressions like`a[i++] *= 2;`where the index ``i'' is incremented only once.and`<<=`also exist; we added`>>=``>>>=`
