whats the difference between || and | (OR) && and &(AND)?

|| and && are logical operators

they evaluate into this and that, or , this or that..


the single ones are bitwise operators

if i have the bit pattern 1111 and 1010 if i do 1111 | 1010 it will or each
bit with its corresponding bit in the other one resulting in 1111 if i do
1111 & 1010 it will result in 1010.

Consider

int a =3D 0;
int b =3D 0;

if((a =3D=3D 1) && (b =3D 1) =3D=3D 0){}

&& instead of & means, that if a !=3D 1, IF returns false without ever =

checking the second statement, whereas with
& both statements would be calculated

&& -> a =3D 0, b =3D 0
& -> a =3D 0, b =3D 1

Same with || and |. If the first statement is true || will ignore the =

second statement, whereas | will check both.

So, for || and && you run the risk that initiations happening in the =

second statements may or may not get done, but you will also benefit fro=
m =

not having to done lengthy initiations if doesn't need to be done since =

the if block would or wouldn't get executed anyway.
