Answer 1

One more important thing to say about your program... You asked there are two values x and y in function...
They are nothing but just parameters or values that your function sum_up(); is gonna use..
This is not necessary that the function accepting 2 parameter must return 2 values ( a function can return only one value when called) ..
In fact there can be a function which even don't return something or don't even receive any parameters ...

Answer 2

The answers is simple.
Your function sum_up();
is taking to parameters x and y..
In function defenition you have written line ...
x+=y;
It means same as x=x+y;
Again it means you are getting sum of x and y in variable x..
And therefore you are returning the calculated value to main function using
return (x) ;
Again you are assigning this returned value to variable ' result ' so result gets value of sum of x and y... and hence your program works..
Hope it will help you😊
