Unique number - query regarding input buffer and for loop

#1

int n;

cin >> n;

int no;

int ans = 0;

for (int i=0; i < n; i++)
{

cin >> no;

ans = ans ^ no;

}

}

After hit enter,

the program asks for the first n.

Then it should play loop for each input number n times an !!?

I didn’t get that the way bhaiya enter input in such style.

Means how it works this way !!!

In console:
7
1 2 3 4 5 6 7

Explain to me the input style used in the program.

Hope you got my doubt.

hello @omkarvp99

first this line will read n . in console it is 7 . so n will be 7.

now this loop will execute n(7) times and in each iteration it will read one number .
so in total it will read 7 numbers one by one.

i.e first it will read 1 then 2 then 3 so on till 7

@aman212yadav, means 1 2 3 4 5 6 7 already stores in kind of memory buffer or what?
