Unable to assign to a variable

Code:

---

for (i=0;i<size;i++)
    {
        for (j=0;j<size;j++)
        {
            if(fscanf(ip_file,"%d",&sudoku[i][j])==1)
            {       
                      //copy to TempArr
                      TempArr[i][j]==sudoku[i][j];
            }
            else
            {
                perror ("fscanf failed on input file.\n");
                // return error
            }
        }
    }

Here I'd like to copy sudoku[][] to TempArr[][] but when I checked the values of TempArr[][], they are completely different. Why this is happening.

When I removed

Code:

---

if(fscanf(ip_file,"%d",&sudoku[i][j])==1)

---

, and replaced with TempArr[][], its working.

Why this is happening and how to handle this situation.

You accidentally used comparison operator == when you wanted to use copy assignment operator =.

Yeah, got it. I wasn't looking at it. Thanks.
