I meant interpret in the sense to figure out what a line of code means. Maybe analyze is a better term. Both the compiler and Intellisense need to do this, although for the compiler that's just an intermediate step.
E. g. in a first pass, all preprocessor commands are interpreted, such as #include, #define, and #pragma. After that, most of the code should be plain C/C++, except template definitions: template code is not complete until you specify the template arguments, and that may only happen much later in the code, or, possibly, not at all in the current compilation unit. The purpose of Intellisense (or one of its purposes) is to give you instant feedback on the correctness of code as you type. But it can't give you that feedback for code that requires other code from an entirely different part of the solution.
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)
The underlining is done by the editor which is part of the IDE. It parses the source files and tries to find the definitions of variables, functions etc., in the source file itself and the included files. Stefan called this process "interpretation".
The parser (the part of the IDE that does this job) is not a compiler. But it is somewhat similar to a compiler by performing identical or similar tasks to check the source code.
A compiler processes his input files not in one go but uses multiple "passes". The parser might not do this or might not perform always similar to a compiler. This may then lead to the behaviour you are seeing.
Completely new to C++ and have been given a task that includes creating an application that uses CString data from a completely separate .h file.
The CStrings consist of info that I need to be able to copy to the clipboard, then be able to paste that text into word etc. I have set up a button in the application so when that button is pressed it executes what I want it to do (read the CString data and copy it to the clipboard).
For a person of my skill level this is difficult and my colleagues do not have the time to support me on this learning project so I thought I could get some advice and pointers here. Any help would be greatly appreciated. I am an apprentice working in software for 2 months.
Hello guys. I am trying to make a simple TSP using Julmar TSP SDK. I am able to make a skeleton TSP which gets detected by Windows and its added line can be seen from Phone.exe.
I want to add a thread in this TSP, which generates fake call to Phone.exe
How do I take it further? Should I add a main()and instantiating all the classes in it, in my .tsp project? Or will I be doing something in TSPUI project (so that I setup few things during manual installation of TSP)? Thanks for giving any pointer.
This world is going to explode due to international politics, SOON.
. But It's wall clock, I'm not sure that I can estimate performance by this way, besides, I need approach which will allow to measure time of each function which I choose. I've heard that there is approach to use CPU-time.
For high accuray difference time measurements with Linux use clock_gettime[^] with timer ID CLOCK_MONOTONIC or CLOCK_PROCESS_CPUTIME_ID. This requires including time.h and linking with the real time library librt (link option -lrt).
Yeah. There is such approach like, count the number of ticks to estimate performance. I do not think that it's panacea.
Richard MacCutchan and Jochen Arndt also correct.
But I guess that you mean universal and independent implementation version. Look here.
I am an innocent bystander of a discussion about how #include directive is handled in IDE.
The IDE in question uses proprietary file "main" name extension (still a text file) and processes #include <header.h> and #include "local_header.h" in that file just fine.
However, when the local_header.h file has <b>another #include <header_1.h></b> in it the compiler "does not see that". That is basically what people who "knows / developed" the IDE are saying.
Including another local file in first local file such as #include "local_header_1.h" is "seen / processed " by IDE.
I was under the impression that #include <file.h > tells the OS to find the file "anywhere" and #include "file.h" tells the OS to search only current / parent directory.
This variant is used for system header files. It searches for a file named file in a standard list of system directories.
This variant is used for header files of your own program. It searches for a file named file first in the directory containing the current file, then in the quote directories and then the same directories used for <file>.
A compiler is not an IDE. An IDE is a front-end to a compiler and it should follow the same rules as the compiler (and pre-processor in this case). If the IDE does not, then it is broken and must be fixed.
Obviously I got the compiler mixed up , so here is the way I view the whole mess.
To get from idea to running code I see these basic blocks
Operating system - with environment configuration
Development application (IDE )
Main file .*ino
"System " includes - example <stdio.h>
IDE "libraries" - example <LiquidCrystal.h>
Local includes - example "MyClass.h"
Compiler / linker (preprocessor)
I think I need to take a look how the compiler handles / finds the path to each include.
I can see if local includes are in SAME directory as the x.ino file it works fine.
But the "system" or "library" includes path are different and that why if fails.
But I want to write code and not troubleshoot the IDE.
Maybe I should use a different IDE.
