What is a lens?

Definition of a lens

Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

This content is ...

Programming in LabVIEW MathScript-Simple While Loop Exercises

Module by: Anthony Antonacci, Darryl Morrell. E-mail the authors

Based on: Programming in MATLAB-Simple While Loop Exercises by Darryl Morrell

Summary: This module provides several simple exercises designed to test and increase your understanding of while loops in LabVIEW MathScript.

Some While Loop Exercises

Exercise 1

How many times will this loop print 'Hello World'?


n = 10;
while n > 0
    disp('Hello World')
    n = n - 1;
end

Solution

10 times.

Exercise 2

How many times will this loop print 'Hello World'?


n = 1;
while n > 0
    disp('Hello World')
    n = n + 1;
end

Solution

This loop will continue to print 'Hello World' until the user stops the program. You can stop a program by holding down the 'Ctrl' key and simultaneously pressing the 'c' key.

Exercise 3

What values will the following LABVIEW MATHSCRIPT code print?

a = 1
while a < 100
    a = a*2
end

Solution

a =
     1
a =
     2
a =
     4
a =
     8
a =
    16
a =
    32
a =
    64
a =
   128

Exercise 4

What values will the following LABVIEW MATHSCRIPT code print?


a = 1;
n = 1;
while a < 100
    a = a*n
    n = n + 1;
end

Solution


a =
     1
a =
     2
a =
     6
a =
    24
a =
   120
