C++ provides two pointer operators, which are Address of Operator (&) and Indirection Operator (*). A pointer is a variable that contains the address of another variable or you can say that a variable that contains the address of another variable is said to "point to" the other variable. A variable can be any data type including an object, structure or again pointer itself.The indirection Operator (*), and it is the complement of &. It is a unary operator that returns the value of the variable located at the address specified by its operand. For example, Example#include using namespace ... Read More

Unary operator is operators that act upon a single operand to produce a new value. The unary operators are as follows:OperatorsDescriptionIndirection operator (*)It operates on a pointer variable and returns an l-value equivalent to the value at the pointer address. This is called "dereferencing" the pointer.Address-of operator (&)The unary address-of operator (&) takes the address of its operand. The operand of the address-of operator can be either a function designator or an l-value that designates an object that is not a bit field and is not declared with the register storage-class specifier.Unary plus operator (+)The result of the unary plus ...

A JTable is a subclass of JComponent class for displaying complex data structures. A JTable component can follow the Model View Controller (MVC) design pattern for displaying the data in rows and columns. A JTable can generate TableModelListener, TableColumnModelListener, ListSelectionListener, CellEditorListener, RowSorterListener interfaces. We can change the background and foreground color for each column of a JTable by customizing the DefaultTableCellRenderer class and it has only one method getTableCellRendererComponent() to implement it.Exampleimport java.awt.*; import javax.swing.*; import javax.swing.table.*; public class JTableColumnColorTest extends JFrame { private JTable table; private TableColumn tColumn; public JTableColumnColorTest() { setTitle("JTableColumnColor Test"); table = ...

Big projects are difficult to manage on mere text editors. You're likely to be more productive and less frustrated if you use an IDE in such cases. There are various types of IDE's and you should select the right one which fits your needs. There is no single best IDE for C++ on Windows. You must choose your tool wisely. Here is a list of popular and IMO best IDEs for Windows.Visual Studio − It is an IDE developed by Microsoft. This IDE has the best in class tooling for building, developing and profiling programs of C++ on Windows. Visual ... Read More

The static storage class instructs the compiler to keep a local variable in existence during the lifetime of the program instead of creating and destroying it each time it comes into and goes out of scope. Therefore, making local variables static allows them to maintain their values between function calls.The static modifier may also be applied to global variables. When this is done, it causes that variable's scope to be restricted to the file in which it is declared.In C++, when static is used on a class data member, it causes only one copy of that member to be shared ...

volatile means two things −- The value of the variable may change without any code of yours changing it. Therefore whenever the compiler reads the value of the variable, it may not assume that it is the same as the last time it was read, or that it is the same as the last value stored, but it must be read again.- The act of storing a value to a volatile variable is a "side effect" which can be observed from the outside, so the compiler is not allowed to remove the act of storing a value; for example, if ...
