Because they are created in memory when the function begins execution and destroyed when the function ends, thus local variables will lose their values between calls in the function in which they are already defined.
What is a Variable in the programming?
Variables are names given to locations in the computer memory, where data can be stored in a program. Based on the values assigned to the variables, this data can be known or unknown.
Variables can also be thought of as 'containers,' as they can hold more than one value. Their sole purpose is to store data and label it in memory, which can then be accessed throughout the program as needed.
In C programming, creating variables is also known as declaring variables. Variables are created in a variety of ways depending on the programming language.

If a program needs to display, for example, some initial data in a Label component when the application starts running, this can be done by including an Init module. True or False
True, By integrating an Init module, a programme can display, for instance, some basic data inside a Label component whenever the application first launches.
What is application?
An application programme, often known as a software application or app for short, is a type of computer programme that is used by end users and is created to do a particular task that is unrelated to the operation of the computer. Examples include word processors, media players, and accounting software. All applications are referred to collectively by the word "application software." System software, which has to do with how computers work, and utility software are the other two main categories of software ("utilities"). Applications can be created as private, open-source, or project-based software, and they can be published independently or combined with the computer as well as its operating system software. Apps are typically referred to as being for mobile devices like phones.

Hong Kong currently dicard approximately 10,000 tonne per day (tpd) of MSW. The HKSAR Government decided to build a modern wate-to-energy incinerator for MSW treatment. The incinerator ha a capacity of 4,000 tpd. Given that the LHV of the MSW in Hong Kong i about 13,000 kJ/kg and the efficiency of the incinerator for electricity generation i 16%. Etimate the electricity production from the incinerator per day at it full capacity
The electricity production from the incinerator per day at it full capacity is 1950 MWh / day
Q = 10, 000 tonnes / day
Capacity of incinerator = 3000 tonnes / day
I tonne = looo kg
Low Heating Value of MSW = LHV = 13, 600 K J / kg
Efficiency of incinerator for electricity generation = 0 .18
Electricity production from incinerator per day at full capacity
LHV x full capacity x efficiency
= 13, 000 KJ/kg x /3000 x 1000 kg* 0 . 18 *1 MWh/3.6 * 106 KJ
1MWh = 3600000 KJ=> IKJ =1 MWh/3. 6 * 10⁶
electricity production = 1950 MWh / day
Electricity generation is the process of producing electricity from main energy sources. Prior to delivery to end consumers or storage, it is the phase for utilities in the electric power sector. Electricity must be "made" because it is not naturally occurring.

You need to connect your doorbell to the electricity in a battery. You should select a material that will accept the flow of electrons.
You can think of a circuit as a loop. In order for electric current to flow through the loop, the \sloop must not contain breaks. In other words, the circuit must \sbe closed. An open circuit has one or more breaks. Most \scircuits have an energy source, wires, a load, and a switch. As \smentioned, energy sources for circuits include generators and \sbatteries.
Machines that generate electricity from mechanical energy are called generators. In this lesson, we’ll focus on batteries. Inside a battery, two kinds of metals build up opposite charges. Negative charges build up on one end of the battery. Positive \scharges build up on the other end of the battery. This is why batteries are marked with \spositive sign (+) and a negative sign (–).

why does discharge in a stream usually increase downstream? group of answer choices because the volume of water in the stream increases with distance from the source because stream velocities increase with distance from the source because the stream is deeper downstream because the frictional resistance decreases downstream
Discharge in a stream usually increase downstream because the volume of water in the stream increases with distance from the source and the main reason of flowing downward is phenomena of gravity and also because stream velocities increase with distance from the source.
What is a Stream and How does it works?
A stream is a body of water that flows on the surface of the Earth. The terms stream and river are frequently used interchangeably, though rivers typically describe larger streams.
Streams require gravity and water to exist. When precipitation falls on the ground, some of it trickles into groundwater, but the majority of it runs downhill as runoff and collects in streams. A watershed, also known as a drainage basin, is the area where water is collected for a stream. Smaller streams frequently merge to form larger streams as they flow downhill. These smaller streams are referred to as tributaries.
