In C, if the result returned without string terminator some test didn't pass. This might help others. I wasted lot of time before figure that out.

Can somebody tell me why i got error on this test?
i printed values by printf on the screen.

Mean = -6.303030
median = -6.000000
case median > Mean -6.000000 > -6.303030
The expression strcmp(result, expected) == 0 is false.

Return is given by function signature int* sumFracts(int lst[][2], int row) and (see function dotest in "Sample Tests") this result is freed.

ok, tnx.

Hi, i'm beginner. Have a problem when try to return result. I calculated N and D correctly, then i create new array int x[] = {N, D}; and trying to return x;
But it doesn't work, every time i got errors, that returned values are not match with expected. What should i return in this function?
Language C. Tnx)

When you ask for help post a question, not an issue.

You need to have the cmath library to use the 'sqrt' operation. Just add:

#include cmath

to the top of your program and it should fix it. Make sure to put "cmath" in angle brackets too.
