A line occurs twice after executing a method. Most thing I know is that the problem comes from tasks[i].getdue() line. If I remove this line totally nothing go wrong but this function makes this bug. I'm guessing this line actually resume the code flow and does not interrupt it.
Is there any way to fix this?
This is my code:
#include<iostream>
#include<string.h>

{

}

And every time I do setdue x after it's done it always show two enter commands : in one single line.
like this one:
enter commmand : addtask 1
enter commmand : setdue 1
enter year : 1
enter month : 1
enter day : 1
enter commmand : enter commmand :
enter commmand : exit
