Input files:
All Source files (.cpp files)
All header files (those specified in the preprocessor directives i.e. all #includes)
All Library files
All Object Files (these are input files to the linker)

Output Files:
Object Files (these are output files from the compiler)
Executables (output files from the linker)

The compiler takes source files and outputs object files

The input of the linker is the output of the compiler i.e it will have a single .o file that contains the main program and a list of libraries.

The output from the linker is the executable file

Something along these lines

Language: C++ (QT)
MyMainWindow::MyMainWindow(){
    feelingsMenu = new QMenu("Feelings",this);
    happyAction->setChecked(true);
    excitedAction->setChecked(true);
    feelingsMenu->addAction("&Happy" );
    feelingsMenu->addAction("&Excited");
    QMainWindow::menuBar()->addMenu(feelingsMenu);
