You should use the function sqrt() to find the square root of a variable.

For example:
c = sqrt(x);

You will need to include the header file <math.h> to use this function though.

Take away this line:

As for the loop, it will keep on prompting you for the next score, until you enter -1 then it will come out of the loop.

Look at your line 60 and line 66. This is not the way you decrement the value.

You should do this:

STAMINA = STAMINA - 2;


or this:

1. Please use "int main()". You are returning 0 at the end of main(), yet you declare that main() return void.

2. You lack a closing brace "}" and a return statement for do_next_op().
