ans is: C complier first checks for main() function. if the complier found the main() function,execution starts at this point.

it has to do with the execution module,well after the compiler compiles the code, the entry relocatable address location is marked, according to the binary format of a particular OS.In C programs, this entry relocatable address location where the execution starts, is nothing but the Main Function.that means the address of the main function is essentially the control transfer address of the binary file generatedif you want to know more or any other doubts, you can mail me ( openangle@gmail.com )

As in C language top to bottom approach isused so prog always starts execution from main( ).

The C programme always start from main function because its a per-defined functions(i.e)its already defined in library fiile(Header files).
