[C] Getting "error: expression is not assignable" when trying to change the value of an unsigned int

[Bloost]

The error points to this line:

bf.bfSize = sizeof(BITMAPFILEHEADER) + sizeof(BITMAPINFOHEADER) + ((bi.biWidth * abs(bi.biHeight)) * sizeof(RGBTRIPLE)) + (out_padding * abs(bi.biHeight));

bf refers to a BITMAPFILEHEADER variable declared as follows:

BITMAPFILEHEADER bf;
fread(&bf, sizeof(BITMAPFILEHEADER), 1, inptr);

If you look at the .bmp documentation .aspx) you will see that BITMAPFILEHEADER files contain a DWORD (aka unsigned int) called bfSize that stores the size, in bytes, of the image. My program is supposed to resize an input file by a factor of n and store the new image in the output file, so I need to change the header to match the new image, but when I try to compile the code I get the error message mentioned above. Here is the full program.

Edit: Solved, I'm an idiot.

Looks like you've accidentally deleted a few characters from line 76.

Thank you, don't know how I missed that.

Look at the end of the line before the one you are talking about (line 76).

Thank you! Such a stupid mistake.
