Are method call statements executed synchronously, in the order in which they are written? [closed]

Answer 1

YES. Function3() waits untill unless Function2() execution is Completed.

if you want to invoke them independently you can use Multi-Threading concept.

EDIT: as suggested in Comments using Task is much better than Thread as it is a higher level concept.

Task Vs Thread

Try This to invoke them Independently:

using System.Threading.Tasks;

static void Main(String[] args)
        { 
            Task t1 = new Task(Function2);
            Task t2 = new Task(Function3);
            t1.Start();
            t2.Start();
        }

here we can not guarantee how the execution flow goes on.because they runindependently.
