Akka really perfect explaination...... Thank a lot

Apo naama return type la vera edhuvum kudukka mudiyaadha? Like char , number , float , double data type .

[@LogicFirstTamil]

It is meaningless to return other types from main function. The purpose of return type in main function is to communicate to Operating system about successful completion of program. So, why do we want to return other types ? You can return other types in user defined functions that you write, not the main function.

Int main use panna return 0 mattum tha potta mudiyuma? Return 1,2...values varuma mam?? Apti vantha entha entha program ku varum

[@subi-crazylove1917]

return 0 means that value finally get return as 0, If u put 1 or 2 .......it return 1(only one time return value) return 2(it return two times)

En void main use panna kudathu?..output varuthe sis athulayum...return value kudukaamaye

[@LogicFirstTamil]

You will get output. But it is not the right way to code. If you dont return anything, your operating system will think that the program did not complete successfully.
