What is error in my code?

I’ve just watched the video on inversion sort.
I’m not able to find the error in my code.

here’s the link to my code: https://ide.codingblocks.com/s/286166

I’ve another question that,

Is the statement,

{

  temp[k++] = arr[i++], 

}

similar to,

{

  temp[k] = arr[i]
  k++;
  i++;

}

???
