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

Dos	Windows
1)it is a CUI	1)it is a GUI
2) it allows the only a single task	2)it allows multi tasks
3) we need to remember commands	3)we don’t want to remember commands
4)it us not possible to share the data	4)it is possible to share the data
5)memory management is easy	5)it is difficult
6)it allows single users	6)it allows multi users
7)size is small	7)size is large

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.

Answers

1. Explain about printf() and scanf() with a program

#include<stdio.h>

#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]);

}

for (i=0;i<5;i++)

{

Printf(“the value in a [%d] is =%d\n”,I,a[i]);

}

getch();

}

(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>

#include<conio.h>

Void main()

{

int n,I,flag=0;

clrscr();

printf(“enter no.”);

scanf(“%d”,&n);

for(i=2;i<n/2;i++0

if(n%i==0)

{

flage=1;

break;

}

if(flag==0)

{

printf(“no. is prime”);

}

else

{

printf(“no. is not prime”),

}

getch();

}

6. Explain logical operators, conditional operators? Write program using these operators.

Operator meaning

&& logical AND

!! logical or

! logical NOT

Logical or operator

Conditional 1 or conditionl2 = result

true true = true

true false = true

false true = true

false false = false

!true= false

!false=true

Precedence of logical operator

Operator priority

! higher priority

&& 2^nd priority

|| 3^rd priority

Program:

#include<stdio.h>

#include<conio.h>

Void main()

{

int a,b,c,d,f;

clrscr();

printf(“%d%d%d\n”&d,&e,&f);

a = d>e && e>f;

b = f>e && e>f;

c = a>b || f>d;

printf(“a,b,c values are %d\n %d\n %d\n”,a,b,c);

getch();

2) write a program to swap two values.

#include<stdio.h>

#include<conio.h>

void main()

{
int a, b, temp;

clrscr();

printf(“enter the no’s\n);

scanf(“%d%d”,&a,&b);

temp=a;

a=b;

b=temp;

printf(“%d%d”,a,b);

getch();

}

4) a) what is jumping statements.

There are few types of unconditional statements

1.break

2.goto.

3.continue

break.

It is used to when the ctrl reaches the break statements . it comes out of the block

Syntax.

break;

goto.

It is used to when the statement is there control goes to label

Syntax.

goto label;

continue.

Continue statements is used to control goes to next iteration

Syntax.

continue;

b) write a program using any unconditional statements.

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

6) a) difference between break and continue statement

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.

#include<stdio.h>

#include<conio.h>

void main()

{

int a,b,c;

clrscr();

printf(“enter the values\n”);

scanf(“%a%b%c”,&a,&b,&c);

if(a= =b&&b= =c)

{

Printf(“values are equal”);

}

else if(a>b&&a>c)

{

Printf(“a is big\n”);

}

else if(b>c)

{

Printf(b is big\n);

}
else

{

Printf(“c is big \n);

}
getch();
