How to run a C++ code in Qt?

Rela

Hi, the previous error was solved. I wanted to have a C++ code results in widget. For reminding in brief, I created a Qt widget project, and I added the C++ code including header and source files to the project. I copied the main.cpp C++ codes in the Qt main.cpp file.

The error was ```

void PS... (char *)': cannot convert argument 1 from 'const char [37]' to 'char *

I changed the definition of the function:

void PS... (char *_sth)

to

void PS... (const char *_sth)

and it doesn't give the error. But, now I want to have some values as result in Application Output , but instead of the non-zero values, they are all zero.
The input data are read from a model.txt file. The path of the text file was also added in the "project" > run of "Desktop Qt 5.6 MSVC2015 64 bit" > "Arguments". Do you know if it is related to the reading input data or not?

How do you read model.txt file?
Is this file found?
Do you have any errors while reading it?
Why don't just debug and see what happens?

@jsulm
In the code, it read using ```

bool ReadModelData(istream &in, functionname &_PS) ...
...
ReadModelData (fin,s)
...

The path of the text file was added in the "project" > run of "Desktop Qt 5.6 MSVC2015 64 bit" > "Arguments". File path
When I debug it just show in the Application output:

Debugging starts
Debugging has finished

and when run the code the results are cpu=0 z=0 ... while they should be some non-zero.
