why do must use assignments (==) in this code?

Question

every one can help me?
#include <iostream>
using namespace std;

int main() {
int n;

cin >> n;

int a=0;
while(n>a){
cout<<n<<endl;
if(n%5==0){
cout<<"Beep"<<endl;
}
n--;

}

return 0;
}

Answer 1

== is actually an equality comparison operator which returns true when both LHS and RHS is equal.

In this perticular program, it is being used to check if the result of ( n%5 ) ,is equals to 0 or not ( indirectly checking if the number *n* is divisible by 5 or not )

Is it necessary ?
of course NO ( I leave the alternatives for you to explore )

----
edit : looks like you are confusing it with assignment operator

"=" is an assignment operator which assigns the value of RHS to LHS

Answer 2

Yasin no

In programming equal to ( assignment operator ) is used to store some data or assign the data

For example :

String me = ig

It means ' me ' is variable and 'ig ' is a literal means 'ig' is store in 'me' variable

Whereas == is an equality comparison operator which returns true when both LHS and RHS is equal.

For example :

2 == 2
True because both values are equal

2 ==3

False because both values are not equal

Answer 3

To check n%5 is equal to 0 ,if yes it will return true else return false

Answer 4

Hello Yasin

== means equal
% modulus operator

n % 5 returns the remainder of n/5
It returns 0 if n is divisible by 5

You enter a number n, let's say 10:
It runs from 10 to 0 and 5 and 10 are divible by 5 so it print's two times "Beep".

Answer 5

but we can also use = to equal 0! can't we?

thanks for answring
