How do you access a variable outside of a loop?

You have defined the variable outside the loop, so the only thing you need to do is to initialize it, as the error message you should get suggests. String name = "not set"; while(loop) name = ... if (condition) // do something to break the loop. // can use name here.

How do you access a variable in a for loop?

Yes, if you define the variable in the main scope, then you can use it anywhere in the main scope. You can choose to use a for loop or a while loop. You can access int i anywhere inside whichever function you defined int i in: Debug. Log ("int i = " + i);

How do you use local variable outside loop in Python?

  1. you have to set the variable a outside the loop – Murillio4 Aug 20 '14 at 13:48.

How do you use a variable outside a function in JavaScript?

JavaScript has global scope and local scope. Variables declared and initialized outside any function become global variables. Variables declared and initialized inside function becomes local variables to that function. Variables declared without var keyword inside any function becomes global variables automatically.

Can you declare a variable in a while loop?

Yes, it is possible, and perfectly permissible to declare height inside the do/while loop, but there's a problem. If you only wanted to use height inside the loop, it's fine. But, the height var would cease to exist when the code exits the loop, so you couldn't use it later. It's a matter of variable scope.

Can you initialize a variable in a while loop Java?

You can't. If you declare a variable inside a loop, then it's only 'visible' inside the scope of that loop. If you need to access it outside of the loop, then define and initialise it before the loop, you'll be able to access it inside the loop after it's done.

How do you call a variable in a for loop?

  1. Declare the variables outside the loops. When you declare them inside the loop, they go out of scope as soon as the loop ends. – ...
  2. You can't "call" a variable. Methods are called. ...
  3. You're creating them inside the for loops. You have to create them before the for loop and then initialize them outside of them. –

What is a for in loop?

In computer science, a for-loop (or simply for loop) is a control flow statement for specifying iteration, which allows code to be executed repeatedly. ... For-loops are typically used when the number of iterations is known before entering the loop.

Can we write a for loop without initialization?

3) The for loop without the condition example

Similar to the initialization expression, the condition expression is optional. If you omit the condition expression, you need to use a break statement to terminate the loop.

How do you make a local variable global in Python?

The global Keyword

Normally, when you create a variable inside a function, that variable is local, and can only be used inside that function. To create a global variable inside a function, you can use the global keyword.

What is local and global variable in python?

PythonServer Side ProgrammingProgramming. There are two types of variables: global variables and local variables. The scope of global variables is the entire program whereas the scope of local variable is limited to the function where it is defined.

What is static variable with example?

The static variable can be used to refer to the common property of all objects (which is not unique for each object), for example, the company name of employees, college name of students, etc. The static variable gets memory only once in the class area at the time of class loading.
