" 'void main() ' vs 'int main()' " and " 'getch();' vs 'return.0' "

[MoMad]

if you know about functions, you will know that main is just another function... so:

void main(void) - is a function that returns nothing and takes in nothing.
int main(void) - is a function that returns an int and takes in nothing.
int main(char*,int) - is a function that returns an int and takes in a pointer to a char and an int

getch() - is only borland specific.

all it does is wait for a user to press <enter>
