Reach way back in your memories to a game we played as kids. It is a simple game for two people where one picks a secret number between 1 and 10 and the other has to guess that number.
The "While" Loop A "While" Loop is used to repeat a specific block of code an unknown number of times, until a condition is met.
For example, if we want to ask a user for a number between 1 and 10, we don't know how many times the user may enter a larger number, so we keep asking "while the number is not between 1 and 10".
If we or the computer knows exactly how many times to execute a section of code such as shuffling a deck of cards we use a for loop. The While Loop The while loop is used to repeat a section of code an unknown number of times until a specific condition is met.
For example, say we want to know how many times a given number can be divided by 2 before it is less than or equal to 1. If we know a specific number, such as 32, we can say 5 times, but for a given symbolic variable "NUMBER" which represents any number in the world, how many times is not known a priori before hand.
In this case, we could use a while loop to determine that answer: The "pseudocode" for such an algorithm is: Like all loops, "while loops" execute blocks of code over and over again.

The advantage to a while loop is that it will go repeat as often as necessary to accomplish its goal. If the action inside the loop does not modify the variables being tested in the loops condition, the loop will "run" forever. How to assure proper input Ask the user to input a value.
A design pattern is the syntax that you have to memorize in order to do well in programming and on tests. The design pattern for a while loop is:I’m going to assume you already know how to program in C, and already know how to program in Matlab.
This post does not teach either language, but will show you how to use them together to get the best of both worlds. >>Hello World! Setting Up Inputs and Outputs.

EDIT: Git We will write a simple HelloWorld program, and load it into the Zynq device on the Zedboard. Cool hu?
This should default to a Hello World example template project. Perfect! There are a great number of project templates that we can pick from. Select the Hello World template, name it.
Hello world is a useless metric of pretty much everything, so it doesn't really make sense to compare it across languages.
With that said, this is an impressive collection and has merit based on that alone.
A "Hello, world!" program is a computer program that outputs "Hello, World!" on a display device. It is typically one of the simplest programs possible in almost all computer languages.
Hello World! Welcome to the ACM "Hello World" project. Everyone has seen the Hello World program used as a first exposure to a new language or environment. We are attempting to collect examples for as many languages and related programming environments (shells etc.) as possible.
