I am having trouble opening the test15.bmp. When I run the program it tries to open a window but crashes. The problem line as much as I could understand is image.loadFromFile(...);
Exception thrown at 0x50E82CC4 (vcruntime140.dll) in
MandelbrotProject.exe: 0xC0000005: Access violation reading location
0x00741000.
This is the exception I get when I use image.loadFromFile("test15.bmp")
instead of the absolute path.
I have linked and included everything as it was described in the SFML tutorials. https://www.sfml-dev.org/tutorials/2.5/start-vc.php
I am using Visual C++(2017)-32 bit SFML and Microsoft Visual Studio 2017.

By default, Visual Studio consider project directory the working directory.
If I'm not wrong,
D:\Visual Studio projects\MandelbrotProject\MandelbrotProject\
in your case. You should ensure yourtest15.bmp
is inside that directory.Just in case, you can check which one is your
$(ProjectDir)
by opening Project Properties->Configuration Properties->Output Directory (any field can be used). Click on the drop-down arrow and Edit. Open Macros and write$(ProjectDir)
