I need help with my C code.

Question

I stuck with these arrays and pointers.

I need to calculate average value of each row of a 2d array and save it in one new 1d array.
I got some outputs like 35982 which are definitely wrong

Answer 1

This should do the trick....

I am a good coder in c but i can tell that using int can give a +-2 error.

If in the end you need integer output only, then cast the array in the end to int before printing

Answer 2

My main 2d array should be float as well?
I think averages need floats because it store the result of a division.
Right?

Answer 3

Absolutely!!

This happens because division neglects decimal values in case of int datatype.

For eg in an array of 3 values 4, 7 and 10, after division with 3, you're left with 1, 2 and 3. And summing them up you get 6 while your answer should be 7!!

Answer 4

Anyhow you can cast the final result to int if you want to avoid the zeroes in the end
