Even though I put in "int main()" correctly in the coding playground, I'm still getting notfied that it is incorrect...what could I be doing wrong?

Answer 1

Its may be because :

You dont have semicolons after each command (;)

Or

because you have the wrong type of parenthesis () {}.

I recomend using a debug tool or comenting out some code to see whats wrong

Answer 2

It's hard to say without seeing the code. It's possible that you have defined main properly. The following is probably the bare minimum
int main () {return 0;}

Answer 3

Got it figured out, thanks for the help!

Answer 4

Yes true

Answer 5

Try

int main() {
<your code>
return 0;
}
