When to use for instead of while loop?
First, it should be noted that both for loop and while loop are used for iteration. However, depending on the scenario; there is preference on one to the other.
The basic syntax of for loop is:
<em>The condition could either be increment or decrement</em>
The basic syntax of while loop is:
<em>The condition could be any condition whatsoever</em>
Analyzing the options one after the other.
1. How many times the loop to run.
The for loop is preferred here because of the simplicity of the for loop.
2. & 3. Both the for and while loops are used for code repetition and to perform number calculations
4. Defined start and end.
From the syntax of the for loop
<em />
A for loop has a definite start and end in its basic syntax and is more preferable to use instead of a while loop.

If you are on a desktop computer you can press the top row key "F3" and a little box will pop up and you can type the word you are looking for in there and it will find that word on the page you are on and take you straight to it.
Answer:
There are up to 12 lights and or plugs on that circuit. A 1000w HPS or Metal Halide light takes 9 amps at 120 volts so you can only run one on a wall outlet circuit. A standard dryer outlet is 220 volts and 30 amps so you can power up to six 1000 watt lights on that circuit.
Complete Question:
1. A wireless technology standard for exchanging data over short distances
2. A particular brand of mobile phone/PDA
3. A network that operates over a limited distance, usually for one or a few users
1. Bluetooth
2. PAN
3. Blackberry
Answer:
1. Bluetooth 2. Blackberry . 3. PAN
Explanation:
1. Bluetooth is a wireless technology standard, used in order to exchange data between mobile devices, like smartphones, tablets, headsets, wearables, over short distances in a one-to-one fashion (which means that it is not possible to build a network based in Bluetooth).
2. Blackberry is a brand of mobile phones/PDAs, very popular a decade ago, because it was the first one to allow mobile users to access e-mails and messages from anywhere, at any time.
3. PAN (Personal Area Network) is an ad-hoc network that it is only available for data exchange at a very short distance, within the reach of a person, i.e. a few meters as a maximum.
It is thought to allow someone to interact with his nearest environment (laptop, tablet, PDA) and it can be wireless (like Bluetooth) or wired (via USB cables).
