why cant i use void instead of int

Answer 1

void doesn't require you to return a value, int does.
When running a program, the value 1 means running to the operating system, 0 is to terminate and -1 is for an error. They are little queues to the OS on what to do with the programs.
For example, computer plugged in to outlet would be a 1, it has power it can run. Computer unplugged would be a 0, no power it can't run. A power outage and PC on, would result on a -1, the PC did not power down appropriately, caused errors.
Hope this answers your question.
