pls explain me?

Question

what is Different between (a>b) && (a>b) (a>b) || (a>c)

Answer 1

Must be a new computer virus. Or why not try out a math forum.

Answer 2

|| is "or" right?, I sort of forgot. The difference is for && to be true both of the conditions should be satsfied. But for || to be true one or both of the conditions can be satsfied. And man the difference really matters. For eg. Username and password require "&&". But for something optional like, let's say, the user has to give his email id and/or his phone no, or can be used.

Answer 3

I think you mean
(a>b) && (a>c)
(a>b) || (a>c)

&&=and
||=or

you need to look at a truth table
For and
false and false = false
false and true = false
true and false = false
true and true = true

For or
false or false = false
false or true = true
true or false = true
true or true = true

You can also substitute the false for 0 and the true for 1.

Answer 4

First one is a "AND" condition, meaning the value to be true the both expressions must be true i.e. a>b and a>c , then & then only the entire expression evaluates to true.

In other expression, if any one expressions evaluates to true the entire expression evaluates to true i.e. if a>b OR a>c.

Answer 5

(a>b) && (a>b) is true only when a is greater than b.
(a>b) || (a>c) is true when a is greater than b or a is greater than c.
when (a>b) && (a>b) is true, (a>b) || (a>c) is true.
but when (a>b) || (a>c) is true you can not say (a>b)&&(a>b) is true or false.
