Question
can a C program has only one main() function or more then one main() function?

Answer
Hi dear krishnaveni!

 C Compiler is devised in such a way it will understand only one main() function no matter how big your programme is .The idea behind this is, main() is the entry point for all the c programes..thats why main() function is limited to one .. if there are more than one entry point .. compiler cannot have track of program execution .. may result in crash or even more dangerous operation say memory violation or stack exhaust .hope this will help you

Thanks and Regards
