The provided code performs the following sequence of operations:

1. x = у;
   The value of у (let's call it y) is assigned to x. At this point, x and у have the same value.

2. у = у+1;
   The value of у (y) is increased by 1. Now, у holds a value that is 1 greater than x.

3. mul(x, у);
   The function mul() is called with the updated values of x and у:

   • The first parameter, x, is the original value of у.
   • The second parameter, у, is the incremented value of the original у (original value + 1).

Summary:

• Assigns the value of у to x.
• Increments у by 1.
• Calls the mul() function with the arguments x (original у) and у (original у + 1).

Without knowing the implementation of mul(), we can't say what it specifically does with these values, but conceptually, this is the behavior of the given code.
