Tips to use Samsung Galaxy Tab

Any new electronic device, especially something as sophisticated as the Galaxy Tab, requires a bit of hand-holding.

Charging the battery:

The first thing that I recommend you do with your Galaxy Tab is give it a full charge. Obey these steps:

Saving a file for older versions of Microsoft Office

If you need to share files with people using older versions of Microsoft Office, you need to save your files in a different file format known as 97-2003, such as Word 97-2003 Document or PowerPoint 97-2003 Presentation.

This special 97-2003 file format saves Office 2007 files so that previous versions of Microsoft Office 97/2000/XP/2003 can open and edit your files.

When you save files in the 97-2003 format, Microsoft Office 2007 saves your files with a three-letter file extension, like .doc or .xls. When you save files in the Office 2007 format, Microsoft Office

Predict the output or error(s) for the following:

  void main()

{

            int  const * p=5;

            printf("%d",++(*p));

}

Answer:

                        Compiler error: Cannot modify a constant value.

Explanation:

p is a pointer to a "constant integer". But we tried to change the value of the "constant integer".

 

Registry

Two Types of Control

Although, in general, the Registry controls all 32-bit applications and drivers, the type of control it exercises is based on users and computers, not on applications or drivers. Every Registry entry controls a user function or a computer function. User functions would include the desktop appearance and home directory, for example. Computer functions are related to installed hardware and software, items that are common to all users.

Some application functions affect users, and others affect the computer and are not specifically set for an individual. Similarly,

Registry

Data File for OS to Hardware/Drivers:

The Registry is a database of all the settings and locations of 32-bit drivers in the system. When the OS needs to access hardware devices, it uses drivers, even if the device is a BIOS-supported device. Non-BIOS-supported devices that are installed must also have a driver. The drivers are independent of the OS, but the OS needs to know where to find them, the filename, the version, and other settings and information. Without Registry entries for each of the devices, they would not be usable.

Data File for OS to Applications:

What is difference b/w static IP address and dynamic IP address?

IP addresses assigned by a DHCP server are static dynamic IP addresses while the one released by IEEE (through the ISP) are dynamic IP addresses. OR

Static address is given by administrator manually.

Dynamic address is given by DHCP server. OR

What the Registry Does?

The Registry is the data file for all 32-bit hardware/driver combinations and 32-bit applications in both Windows NT and Windows 95. Sixteen-bit drivers do not work in NT, so all devices are controlled through the Registry, even those normally controlled by the BIOS. In Windows 95, 16-bit drivers will continue to work as real-mode devices, and they use SYSTEM.INI for control.

Sixteen-bit applications will work in either NT or 95, and the applications still refer to WIN.INI and SYSTEM.INI files for information and control.

Without the Registry, the operating system would not have the necessary information to run, to control attached devices, to launch and control applications, and to respond correctly to user input.

What is the Registry?

The Registry has been made out to be a phenomenal mystery probably due to the CLSID keys alone and as such has inspired a number of books, faqs websites etc. It is very unfortunate that Microsoft has chosen to deal with the Registry and Registry editing as a "black art," leaving many people in the dark as to the real uses of all the settings in the systems. Microsoft's refusal

Real data types

The floating point data types are called "real data types".

Hence float, double, and long double are real data types.

How would you round off a value from 1.66 to 2.0 in C-language?

main()
{
printf("%f",ceil(1.66));
}

Output: 2.0
