Well. You are closing the file inside the loop aswell. You open the file, then close it. Move the

myfile2.close(); outside the loop.

Also, never use loops like this while(true){
Its not good, use actual conditions.

Its cuz of this while(true){ Why is it even true? That makes no sense. You need to tell the program when you want the while loop to exit.

How? The loop serves as my timer. Idgi. I'm sorry X_X

When you do while(true) you get an infinite loop. You never want that. It will never exit the loop. You have to tell the loop to exit at some point, otherwise it wont work.

Can you give an example? I can't see the logic :(
Mar 26, 2015 at 6:33pm

for example. If you change the loop to this

Your program should work, although maybe not exactly as intended, cuz its a bit of a weird setup.
