Section-B
4) a)
Describe the installing of new software using control panel ?
Control panel is parts of a micro soft
windows graphical user inter face.
Control panel allows users to view and modify
the system settings to control panel and devices of the system
Steps :
·
click
on the start button & go to the control panel
·
Click
on add or remove programs option then it will display the 3 basic options on lift side of the picture them click on add
new programs then there will display two options.
i.e. a) Adding programs from cd-rom pr
floppy:
if the program we want to install us on a CD-ROM or on a
floppy disk on the CD or FLOPPY button and a screen will appear us at introduce
the CD or FLOPPY in the corresponding drive normally it will ask a questions
regarding where the programs is to be installed we recommend to accept the
folder that is suggest
this is a one way to install a program a CD
but in the majority of the cases it is not necessary, it is easier and quicker to just put the CD un and let the
program in the CD drive it do it automatically. The result is the same and we
will save ourselves having to reach this screen to add new programs.
b)
write difference between dos and windows

5)a)
what is defragmentation?
Defragmentation is defined as the organizing the disc space in proper manner.
b) Write the procedure to install a hard ware
using control panel
The assistant searches for new hardware.
Normally it will not find anything new. Now it asks if we have already
connected the new hardware if we answer NO a screen will appear indicating the
assistant has finalized or ended since there is nothing to detect.
The hardware that we want to install will
probably not be on list show. the list to find a line that says “add new
programs” and click on this line. Then click next.
There are two options
The first one is to have the windows look
again for new hardware. Nevertheless, we can try again and we will get the
screen that is shown here.
Press the next button untells you get Finish
button. Then the new hardware will be
installed.

#include<conio.h>
void main()
{
int a,b,sum;
printf("Enter
the two number\n");
scanf("%d,%d",&a,&b);
sum=a+b;
printf("sum
of two numbers is %d",sum);
getch();
}
2. Explain
about basic data types? Write a program using basic data types?
There are four basic
data types:-
DATA TYES BYTES RANGE
int
2bytes -32,768 to 32767
float 4bytes 3.4e-38 to 3.4e+38
char 1byte -128 to127
double 8bytes 1.7e,-308 to
1.7e,+308
3. Define
constant variable and identifier and rules.
CONSTANT:
If we declare any
variable as a constant the value of the variable will not be changed or
modified.
SYNTAX:
datatype
constant variable = value;
EXAMPLE:
int const a=10;
VARIABLES:
A variable is a identifier. It is used
to store the data. It store only one value.
SYNTAX:
datatype
variable;
EXAMPLE:
int a;
a=10;
4. (a).
How do you declare arrays and strings , explain in a program
An array is the collection of elements of
different datatypes of homogenious data
Examples: int a[5];// declaration an array of a type
int
·
array name follows the same rules of
naming variable this name can be used only to refuse the array and as an
ordinary variable
SYNTAX:
Datatype variable[size];
PROGRAM:
#include<stdio.h>
#include<conio.h>
void main()
{
int i,a[5];
clrscr();
for (i=0;i<2;i++)
{
scanf(“%d”,&a[i]);

(b) Define the terms (i) break (ii)
continue (iii) null statement.
Break:
Break statement is used in
generally with loops and switch statement.
It is used to terminate a loop.
SYNTAX: break;
Continue:
The
continue statement is used for doing the next iteration.
SYNTAX: continue;
Null statement:
Statement is always terminated
by as semicolon. A semicolon with nothing preceding it is also available
statement. Caused the null statement.
5. Define
an looping statement with program
#include<stdio.h>

for(i=2;i<n/2;i++0
if(n%i==0)
{
flage=1;

it comes out of the block
Syntax.
break;
goto.

goto label;
continue.
Continue statements is used to control goes to next
iteration
Syntax.
continue;
5) write the structure of “C” program in detail.
Documentation section
Link section
Definition section
Global section
Main() section
Sub program section
The “C” program contains the
3parts
Part-1
Documentation section .
* It contains the comment lines.
*it is optional
Link section.
- it contains the header files.
Ex #include<stdio.h>
#include<conio.h>
Definition section.
- The definition section contains the macros.
- It is optional
Global section.
- If the variable is declared before the function then
it is known as the variable
- Ex: int a;
void main()
{
statemaets………………
}
Part-2
main()
- ”C” program starts from the main() section
- Main() contains the blog of the statements
- Main is the special
user defined (), it is not predefined in any header files
Part-3
Sub program section.
- It is a user defined function
Break
|
Continue
|
1) it executes the loop
|
1) it continues the loop
|
2)the main loop of break
statements is escape from the block
|
2)generally use of continue
statements is to prefer next iteration of the loop
|
3)syntax- break;
|
3)syntax- continue;
|
4)break can be used in
forloop,whileloop, do whileloop and switch statements
|
4) continue can be use in for
loop, while loop, do while loop but not in switch statements.
|
5) it is more useful than
continue
|
5)it is less useful than break
|
b) write any program using else –if.

one function to another function
5.
It provides program execution speed

Structure
|
Array
|
1. It
is a collection of elements(variables) of different data types
|
1. It
is a collection of elements of same data type
