cout << "\n -addition result is: " << c;

cout << "\n -operarion finished"
<< "\n -thank you for using my app";

return 0;
}

Answer 1

You are adding values before you even get them from the user. Thus , they a and b give out garbage values as they are not assigned.

So ,
write like this,

cin >> a >> b;
int c = a + b;

instead of

int c = a + b;
cin >> a >> b;

And please refer the link to your code instead of copy/pasting it. Makes it easy to debug.

Have a good day,

Answer 2

Hmm

Answer 3

Because you are adding c=a+b before taking input from user.
so correction should be:
cin>>a>>b;
int c=a+b;
