MICROSOFT WORD
AIM:
To create a document that reflects the newspaper format using Microsoft word.
Word processor is used to produce documents for business or personal use such as newsletter, reports, letters and essays. We might say that a word processor is an intelligent typewriter. We can type a whole page, make corrections (editing), use up paragraphs in different styles and shapes and columns (formatting) and also check spelling, find and insert synonyms for a word (Thesaurus) and process it in many more ways before we actually put that page to print.
FEATURES OF WORD PROCESSOR
The following are the main features of a word processor:
Fast
Editing features
Permanent storage
Formatting features
Graphics
CREATING A WORD DOCUMENT
PROCEDURE:
To enter Microsoft word, Click “start” button then click “program” from “programs” menu then click “Microsoft word”
For opening a word document do the following. Click “file” menu from the menu bar. From this file menu click “new” option. This will display the new document.
Then for the newspaper format there must be a “header and footer” for giving heading and page number. This is done by clicking “view” from the menu bar, from this click “header and footer” option.
Then enter the heading in the header portion and change the “font size” to big size and then click “B” button on formatting tool bar so that the header appears bold.

void main()
{
union emp
{
char name[25],design[20];
int salary;
}e[5];
int i,no;
clrscr();
printf("Enter the no.of employee:");
scanf("%d",&no);
for(i=0;i<no;i++)
{
printf("\nEmployee[%d] information:\n",i+1);
printf("Enter the name:");
scanf("%s",e[i].name);
printf("Enter the designation:");
scanf("%s",e[i].design);
printf("Enter the salary:");
scanf("%s",&e[i].salary);
}
getch();
}
Output:
Enter the no.of employee:2
Employee[1] information:
Enter the name:Dhanam
Enter the designation:Professor
Enter the salary:30000
Employee[2] information:
Enter the name:Amudha
Enter the designation:Assit.Prof
Enter the salary:25000
Result:
Thus the above experiment has been executed and output was verified Successfully.
FUNCTIONS & RECURSION
12. MENU DRIVEN CALCULATOR USING FUNCTIONS
AIM:
To write a C program to perform the arithmetic operations using functions
ALGORITHM:
Step 1: Get the values A and B
Step 2: Display the choices and also get the option
Step 3: If OPTION IS 1, call function ADD (A, B) and assign the result in D.
Step 4: If OPTION IS 2, call function SUB (A, B) and assign the result in D.
Step 5: If OPTION IS 3, call function MUL (A, B) and assign the result in D.
Step 6: If OPTION IS 4, call function DIV (A, B) and assign the result in D.
Step 7: Call function DISPLAY (D)
ALGORITHM FOR ADD (A, B):
Step 1: Add the values of A and B and assign the result in G
Step 2: Return the variable, G.
ALGORITHM FOR SUB (A, B):
Step 1: Subtract B from A and assign the result in G
Step 2: Return the variable, G.
ALGORITHM FOR MUL (A, B):
Step 1: Multiply A and B and assign the result in G
Step 2: Return the variable, G.
ALGORITHM FOR DIV (A, B):
Step 1: Divide A by B and assign the result in G
Step 2: Return the variable, G.
ALGORITHM FOR DISPLAY (D):
Step 1: Display the value of D.
Program:
#include<stdio.h>
#include<math.h>
void main()
{
int a,b,c,ch;
clrscr();
printf(“Arithmetic Operations using Menus\n”);
printf(“Enter the two values for calculation::”);
scanf(“%d %d”,&a,&b);
printf(“\n\t\tMENU\n “);
printf(“\n Enter the Choice of Operation \n 1.Add\n2.Sub\n3.Multiply\n4.Division\n5.Remainder\n\n”);
scanf(“%d”,&ch);
switch(ch)
{
case 1:c=a+b;
break;
case 2:c=a-b;
break;
case 3:c=a*b;
break;
case 4:c=a/b;
break;
case 5:c=a%b;
break;
default: exit(0);
}
printf(“Result=%d”,c);
getch();
}
Output:
Arithmetic Operations using Menus
Enter the two values for calculation::34 98

Result=34
Result:
Thus the above experiment has been executed and output was verified Successfully.
13. FIBONNACI SERIES
AIM:
To write a C program using recursion generate the Fibonacci series up to for the given number.
Series:
0 1 1 2 3 5 8 13
ALGORITHM:
Step 1: Enter the number N.
Step 2: Initialise f=-1 and s=1
Step 3: Call the recursive function FIBO, with N, f and s as arguments.
ALGORITHM FOR FIBO (N,f,s):
Step 1: If N is greater than Zero
1.1 no=f+s
1.2 print the no
1.3 Call the recursive function FIBO, with N-1, s and no as arguments.
Program:
#include<stdio.h>
#include<conio.h>
void main()
{
int num,fib=0,a=0,b=1,i;
clrscr();
printf(“Enter the number:”);
scanf(“%d”,&num);
printf(“\n Fibonacci series\n” );
if(num==0)
printf("0");
else
{
for(i=0;i<num;i++)
{
fib=fib+a;
a=b;
b=fib;
printf(“%d\n\n”,fb);
}
}
getch();
}
Output:
Enter the number 8
Fibonacci series

Result:
Thus the above experiment has been executed and output was verified Successfully.
14. FACTORIAL
AIM:
To write a C program using recursion to find the factorial of the given number.
ALGORITHM:
Step 1: Enter the number N.
Step 2: Call the recursive function FACT, with N as an argument.
Step 3: Print the returned value of a function FACT
ALGORITHM FOR FACT (K):
Step 1: If the number K is equal to 1, then return 1
Step 2: Otherwise call it recursively with N-1 as an argument and return it.
Program:
#include<stdio.h>
#include<conio.h>
void main()
{
int fact=1,i,num;
clrscr();
printf(“Enter the Number”);
scanf(“%d”,&num);
for(i=1;i<=num;i++)
{
fact=fact*i;
}
printf(“The factorial is %d”,fact);
getch();
}
Output:
Enter the Number 7
The factorial is 5040
Result:
Thus the above experiment has been executed and output was verified Successfully
