Dec 13, 2011 · For example if you use __FILE__ with your definition to produce a diagnostic in an inline function defined in a header file, the runtime diagnostic will report the name of the file passed to the compiler instead of the name of the include file, whereas the line number would refer to the include file.
The spaces are significant. You created a variable named 'location ' with a value of ' "bob"'.Note - enclosing single quotes were added to show location of space.
May 30, 2014 · The besty practice is to use '/' and a so called 'raw string' to define file path in Python. path = r"C:/Test.py" However, a normal program may not have the permission to write in the C: drive root directory. You may need to allow your program to do so, or choose something more reasonable since you probably not need to do so.
You can optionally add a new file-name. #line 100 "file.c" It's only rarely useful. But if it is needed, there are no alternatives I know of. Actually, instead of the line, a macro can be used too which must result in any of the above two forms. Using the boost preprocessor library, you can increment the current line by 50:
Jan 11, 2013 · If you want to share a define between two source files, move it to a header file and include that header from both source files. mydefines.h: #ifndef MY_DEFINES_H #define MY_DEFINES_H #define A (1) // other defines go here #endif // MY_DEFINES_H source1.cpp: #include "mydefines.h" // rest of source file source2.cpp:
Apr 9, 2023 · @JackO'Connor that's what I do. You certainly do not want to put "C:\" in the middle of the file name. Besides, you can use os.path.normpath before or after a join, to make sure the path gets printed nicely. –
May 16, 2011 · I have a .ps1 file in which I want to define custom functions. Imagine the file is called MyFunctions.ps1, and the content is as follows: Write-Host "Installing functions" function A1 { Write-Host "A1 is running!" } Write-Host "Done" To run this script and theoretically register the A1 function, I navigate to the folder in which the .ps1 file ...

The cost of opening a file, discarding all its contents, and closing it over and over might not sound like much, but for a large header included transitively by hundreds of other headers (e.g. windows.h, the low-level stuff providing simple type definitions like stdint.h, types.h, etc.), the difference between opening it exactly once per source file and opening it a hundred times (where only ...
What IS a file? A file is an abstraction. It's an adress somewhere in memory that indicates the first byte in a series of bytes (it can also be fragmented if it's a large file). A stream is also a memory location where bytes are written and bytes are read. In that sense, it is like a file in that you can write and read from it.
