Why am I getting this problem and how can I fix it? From my point of view I already declared it. Please see the image.
Thanks a lot!
You have an extra semicolon between the for statement and opening brace. That makes the for loop have an empty body, and the braced expressions have no idea what angle is supposed to be, since it truly is out-of-scope.

This is used here do {....} while(ch!=?.?); what does ch!=?.? mean here can anybody please help with it.
It's a syntax error with both clang and gcc.
#JonathanLeffler is usually right and I think he nailed the root cause. I used to see this when text was being copied from Microsoft Word to the web (lack of transcode from a Windows code page to ascii/utf8?).

My code was converted to these random characters at some point after I saved my program using Vi. I did this project for a grade in one of my college courses and didn’t get any credit, despite the fact that I spent hours working on my code for this to happen. If anyone knows how to convert it back to C++ I would be thankful.
Turns out I had saved my file under the wrong folder and I was able to recover my original file. Thanks to all for helping out with this! It seems like it always tends to be something so simple...

Why is g++ giving an error like this?
blahblah.h:80:10: error: decomposition declaration not permitted in this context
float[NUM_OUTPUTS] output_buffer;
(Already solved, but creating this because there's no good google hits for this error text, and the error message is inscrutable.)
In C++ declarations, the array size goes after the variable name, not after the type:
float output_buffer[NUM_OUTPUTS];

I think I saw something on using this to truncate test as a filter, but I've seen to no idea how to use it. Using as xx|do_trucate(20) gives the following:
TemplateAssertionError: no filter named 'do_truncate'
What is the correct usage?
Doh, from the spec I saw
do_trucate
http://code.nabla.net/doc/jinja2/api/jinja2/jinja2.filters.html
But in reality, its just truncate

I declare in a header traductionCSV.h the function
static QVector<struct variableDurSupervision>
listVariableDurSupervison(std::string fichierCSV);
I write it in my cpp, then I want to use it in another file supervision.cpp, so I call it like this :
remplirDurCellule(
traductionCSV::listVariableDurSupervison(
"../../FichierCSV/ListeVariableSupervision.csv"
)
);
But it won't work, I got this error :
undefined reference to traductionCSV::listVariableDurSupervison(std::string)
I properly include all the file, so I don't understand.
Thank you.
You are probably missing the class name when you are defining it in cpp. It should be like :
QVector<struct variableDurSupervision> traductionCSV::listVariableDurSupervison(std::string fichierCSV)
{
...
}
This rule applies both to static and non-static functions of a class.
