Answer 3

Hello Jaqueline,

Your name sounds familiar to me.. so I'll to take the risk of answer you in Brazilian Portuguese, okay ?

But if others are reading this question and also wanna know the answer, the operator " == " is a boolean expressions and compare if something ia true or not. You can read this:

___(A)_____ == _____(B)______:

If was true that (A) is equal (B) ... than: (do s something).

The operator " = " is common used to define something.

example

number = int (2)

print (number)

>>>> 2

Oi Jaqueline,

Seu nome soa familiar, então eu vou me arriskar respondé-la em Portugues do Brazil, tudo bem ?

O operador == é para comparar sentenças, ele responde se o valor é verdadeiro ou falso.
Lembra de lógica ?
Nem todo mundo estuda isso, mas os operadores == tem a função de comparar o valor lógico da sentença.

Isso é muito útil quando você precisa tomar decisões em cima de outras dependentes do "input" ou da resposta do usuário.

Answer 4

if u want to know why ==
its a syntax / thought
u can take it as below :
suppose its in code -
if a==h :
do this
now compiler will check if the value of a and h are equal...
so first qual to check a's value next for h's value...
like this
a=5=h....
interpreted as a==h..

now as it is a syntax provoked by a certain direction of thought of how check two values its not 100% logical to everyone..

Answer 5

this is so because this is a c++ there =karna assignment and == means giving a particular value .

Answer 6

=
is assigning operator to assign value
it works from right to left
x=4
4(right) is assigned to x(left)

== is checking operator for values / types both for rhs and lhs
