Yes, your solution is correct. Could you please explain it.

The key point here is the line static int x;

static keyword will store the variable x in static area, and therefore it will be initialised only once. That is when you execute the function first time then only this line will be executed, and in every other call, it will be skipped.

now, the x in print1() and print2() are different.

print1() //first time

x will be created, and 15 will the final result of first execution.

print1() //second time

x is already created, and 20 will the final result of second execution.

similarly try to execute print2().As it overwrites x=10, so everytime the result will be 15 only.
