scanf("%d", &t1);
while (t1 > 0){
    printf("%d\n", t1);
    t = t1 % 60;
    t1 = t1 / 60;
    printf("%d : %d\n", t1, t);
    scanf("%d", &t1);
}

// no need for a while loop as you only have a single value to convert
int minutes = t1 % 60; // remainder = 3
int hours = t1 / 60; // 3663 / 60 = 61

1. Use the existing header and source files from the examples and add them to your project. Then call the function using the name and include the header file in the source files where you call it.
   
2. Convert the examples by implementing all the code in Qt classes (source and header).
   

// MainWindow.h
 class MainWindow : public QMainWindow
{
    Q_OBJECT
public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
    // No calling convention here because this is a Qt based C++ class member
    void CliCompletion(void *usrPtr, int opCode, int opResult);
    // ...
};

//MainWindow.cpp
#include "snap7.h"
#include "MainWindow.h"
// Other includes

void MainWindow::CliCompletion(void *usrPtr, int opCode, int opResult)
{
    // Call the global implementation from other source file or library
    ::CliCompletion(usrPtr, opCode, opResult);
}
