C++ Uniform Initialization

-

 

Uniform initialization

These are the various types of initialization:

  1. Value initialization where object is set to default value -> T obj{}
  2. Direct initialization -> T obj{v}
  3. Copy initialization -> T obj = v

Copy initialization should be avoided for user defined types to prevent potentially unnecessary copies

Advantages of uniform initialization

  1. Forces initialization
  2. Uniform syntax; direct initialization for array types
  3. Prevents narrowing conversions:
float f{2.0};
int k{f}; //throws narrowing warning or error

QTreeView and QTableView dynamic changes

Dynamically adding items to  QTreeView  and  QTableView Create the UI as follows, with the treeview on the left hand side and the table view on the right hand side. Notes The header file contains the models and the selection models for the tree view and the table view: QStandardItemModel * treeViewModel ; QItemSelectionModel * treeViewSelectionModel ; QItemSelectionModel * tableSelectionModel ; QStandardItemModel * tableModel ; In the .cpp file, the tree view models and table view models are set as the models for the selection models. treeViewSelectionModel -> setModel ( treeViewModel ) ; tableSelectionModel -> setModel ( tableModel ) ; The following code illustrates how to dynamically add a new row to the treeview. void MainWindow :: updateTreeView ( ) { QStandardItem * newRow = new QStandardItem ( QString ( "inserted row" ) ) ; QList < QStandardItem * > newRows ; newRows . append ( newRow ) ; aut...

C++ strings and string_view

-
C-style strings C style strings should be avoided except when interfacing with C libraries. C string library functions provide no bounds checking and memory allocation support. They are represented as an array of characters. Last character of the string is the null character  \0 , so that code that uses the string knows where it ends. The space needed for a string is always one more than the number of readable characters. String Literals Strings written with quotes around them are string literals. They are stored in a read-only part of memory. Because they are stored in readonly sections, attempting to modify string literals is  undefined behavior . Example: char * str = "world" ; str [ 0 ] = 'y' ; //undefined behavior If the code respected the standard and assigned the string literal to  const char* , the compiler will catch attempts to modify string literals: const char * str = "world" ; str [ 0 ] = 'k' ; //compiler will f...
