+Copy
+cuda.cu:52:10: fatal error: helper_functions.h: No such file or directory
+ #include <helper_functions.h>
+          ^~~~~~~~~~~~~~~~~~~~
+compilation terminated.
+indicates that the compiler cannot find the helper_functions.h file. This is because the #include <helper_functions.h> directive is looking for the file in the system's include paths, but the file is either not in those paths or is located in a different directory.
+
+Solutions
+1. Use #include "helper_functions.h" Instead of #include <helper_functions.h>
+Angle brackets (< >) are used for system or standard library headers.
+
+Quotes (" ") are used for local or project-specific headers.
+
+If helper_functions.h is in the same directory as cuda.cu, change the include directive to:
+
+3. Verify the File Exists
+Double-check that helper_functions.h exists in the specified location. If the file is missing, you'll need to obtain or recreate it.
+
+4. Use the Correct CUDA Samples Path (if applicable)
+If helper_functions.h is part of the CUDA Samples, ensure you have the CUDA Samples installed and include the correct path. For example, on Linux, the CUDA Samples are typically located in /usr/local/cuda/samples/common/inc. You can include this path like so:
+
+Use #include "helper_functions.h" for local files.
+
+Use the -I flag to specify the directory containing helper_functions.h.
+
+Ensure the file exists in the specified location.
