For a reference data type, that default value is Nothing (Visual Basic). Reading a reference variable that has a value of Nothing can cause a NullReferenceException in some circumstances.Passing an argument to a procedure ByRef exposes the variable underlying the argument to possible modification ...

Modernish clears the PPs upon completion of the loop, but if the loop is exited prematurely (such as by break), the last chunk survives. On shells with the KSHARRAY capability, an extra variant is available: --xargs=arrayname which uses the named array instead of the PPs. It otherwise...
It's always bit-by-bit copy. Why would you need that, leaving performance considerations aside? So the only thing value types are useful for is performance. Array of structs is layed out contiguosly in memory, which means that when performance is an issue an you can convert some of yo...

function execution. For example, the File.delete() method returns false if the file could not be successfully deleted (rather than throwing an Exception). If you don't check the result, you won't notice if the method invocation signals unexpected behavior by returning an atypical return value...

When you use an array, first you need to declare a reference variable that points to the array. Then you need to create the array object using the new statement, specifying how big you want the array to be. Then you can set the elements in the array. Here’s an example of code that...
