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.

Probably bc it's an app, not a computer program. it probably just has enough content to show the current material.

it depends on your compiler you can use void or int both according to the software you are working on

In void main you can use only comments. In into main you are able to use numbers for various programming. Read about data types you will understand the difference.

void means null and int means integer type. u can use both but it depends upon the type of compiler or software u r using like code:: blocks u can use void and int but sometimes it is doesn't run the program.

int is used when your function is receiving integer value from another function.
