Is it compulsory to write int main instead of void main while recursion?

Answer 1

main function by standard does return int, old compilers may accept main to return void, but it's just non-standard. And although it is possible, it is not considered a good design to have a code that enters main function recursively, one can design a loop within main to repeat a certain task rather than calling the main again to go round and round.
