Can we use floating variables in if statements in C?tccicomputercoaching.com

Yes, we can use floating variable in if statement but you have to be very careful while initialising the condition C Language.

Comparisons between floating-point values (including comparisons with zero) are easily sent “off” by truncation/rounding errors.

Yes. You can use. But a direct comparison will never result in a true condition.

Remember that floating point values are hardly precise. So what you can do is along with the float value you are comparing, declare another value that serves as an upper and lower bound to your value,

For example:-

Float a=6.7, b=5.8;
if(a==b)
{
printf("same");
}
Float a=1.0;
If (a==1) // this will be wrong in this case as condition will never be true
To do this correctly you have to write like this
If (a==1.0){
}

3	nested loops You can use one or more loop inside any another while, for or do..while loop.

3 sections of Loop:

1. Initialization:

i=1

2. Codition

Different types of Computer Networks-tccicomputercoaching.com

Different types of Computer Networks

1. Personal Area Network (PAN)

The smallest and most basic type of network, a PAN is made up of a wireless modem, a computer or two, phones, printers, tablets, etc., and revolves around one person in one building.

2 . Local Area Network (LAN)

LAN is a small and single site network. A LAN connects network devices over a relatively short distance.

3. Wireless Local Area Network (WLAN)

A Wan is a geographically dispersed collection of LAN's. The Internet can be considered a WAN as well. A WAN like Internet, can expand most of the World. A network device called a router connects LAN's to a WAN.

4. Metropolitan Area Network (MAN)

It is a data network designed for a town or city. It connects an area larger than a LAN, but smaller than a WAN, such as a city, with dedicated or high performance hardware. Its main purpose is to share hardware and software resources by the various users.

5. Wide Area Network (WAN)

His allows computers and low-voltage devices to be remotely connected to each other over one large network to communicate even when they’re miles apart.

Encapsulation in Python-tccicomputercoaching.com

In an object oriented python program, you can restrict access to methods and variables. This can prevent the data from being modified by accident and is known as encapsulation. Let’s start with an example.

The private attributes and methods are not really hidden, they’re renamed adding “_Car” in the beginning of their name.
 
Class with private variables. Variables can be private which can be useful on many occasions. A private variable can only be changed within a class method and not outside of the class.

class Car:
def __init__(self):
self.__updateSoftware()
def drive(self):
print 'driving'
def __updateSoftware(self):
print 'updating software'
redcar = Car()
redcar.drive()
#redcar.__updateSoftware() not accesible from object.

This program will output:

updating software driving
