What is difference between OR (|) and Logical OR (||) ?

1. Logical OR Sign is || and AND Sign is  |.

2. Both work is same but Operation Method is Different 

for example 

if(a==10 || b==10) 

here if a =10 then condition is Satisfied and not going checking values of B. 

Moral One Operation for checking second i.e B values decrasesand in AND & operation 

if(a==10 | b==10)

here if a ==10 then also it is checking B value i.e  it is not necessary.    
    
Logical OR(||) is Best.    

What is difference between AND & and Logical AND &&?

1. Logical AND Sign is && and AND Sign is  &.

2. Both work is same but Operation Method is Different

for example

if(a==10 && b==10)

here if a =10 then only it going for  checking b value

if a !=10 then condition is not satisfied.

Moral One Operation for checking second values decrases

and in AND & operation

if(a==10 & b==10)

here if a !=10 then also it is checking B value it is not necessary.

Logical AND(&&) is Best.
