This is all good and well, but what are the implications of this? Well, let's say you have an application that remembers a name, which can also be changed with achange_name()function. Thenamevariable is defined globally, and locally within the function. As you can see, the function fa...
Scala example of local variables scope In this example, the code tries to access a variable outside its scope. This local variable cannot be used outside of the function. classStudent{varroll=2343;privatevartotalMarks=500// this cannot be accessed by the objectdefprintinfo(mark:Int){println...
This is the expected output. But what if you want to access the variablevalueoutside of theifstatement code block? Attempt to access a variable outside the code block in which it's declared In the Visual Studio Code Editor, create a new code line below theifstatement code block. ...
In the following example, we are trying to access "b" outside of fun1(), where "b" is defined within fun1(). So, for the purpose of the function's scope, the accessibility of the variable is within this function only. From outside of that function it will not be accessible. ...
