why don't we put return1; or return2; or any other integer value in return statement why we always put return0; at the end

Answer 1

Since your code isn't returning anything therefore we write return 0 statement; as the datatype of main is integer so you can return any integer number(or nothing at all, just don't write the return thing). It's just like "why we use void?"=because we are returning nothing at all. Simple.

Answer 4

You don't have to return 0, you can return anything you want.
In main return 0 is often used for successful execution of the code and other return values for different errors or problems that forced the program to manually terminate.

Integers normally range from -2147483648 to 2147483647, so as long as you stay within those bounds it will work.

Answer 10

This question is commonly asked. Here is a short answer for you.
1- Functions can return values. e.g. y = f(x). The value of x is processed by function f and the return value is stored in variable y
2- Main is a function, but what happens to the returned value? There are multilple ways to know the returned value. But the important thing to know is that, by convention, we interpet the value 0 to mean that no error occurred.

Answer 11

code and let us know what you get.

Answer 13

actually @sonali Sharma u ques is very good and here is ur ans we use return1 or return 0 because there are only two possibilities whether it will return a value or not when it doesn't return value we use return 0 and when it does we write just return or return 1. and as we know main function does not return value but when we use INT main then it should return a value due to function prototype so we use return 0
