How can I test out header files and related C++ source code?

[A Former User]

I try to add new function for my Qt program with CPP and header file. But I'm not quite sure if I get it right. Like to test it out on Qt Creator, but errors and warnings keeps popping up. I don't know what I I've done wrong.

header:

#include <QApplication>
#include <QObject>
#include <QWidget>
#include <QString>
#include <iostream>

#ifndef TEST_H
#define TEST_H

class test{
public:
static bool check(const QString& data);
static void run;
public:
static unsigned char* pTr = NULL;
}

Hi and welcome.

I added some comment to the code to show the changes to make it compile.

I wonder if you are aware of using static in classes has a completely other meaning than
in good old C.

:)

#ifndef TEST_H
#define TEST_H
class test{
public:
static bool check(const QString& data);
static void run(); <------------- must have () when function
public:
static unsigned char* pTr = NULL;
}; <---- must end with ;
#endif <----- was missing

Read the error messages. They tell you what's wrong.

@mrjj No, I didn't know that, thanks for pointing my errors out. :)
