display(&x,&y);

printf(nAfter the swapping the value of,x=%dty=%d,x,y);

}

Display(int *a,int *b)

{

int t;

t=*a;

*a=*b;

*b=t;

}

OUTPUT:

Enter the two numbers10 20

The entered number for x and y are, x=10 y=20

After the swapping the value of, x=20 y=10

Result

The elements are swapped using arrays and functions successfully.

Ex.No. 18 MARK SHEET USING STRUCTURES

Date.

Aim

To write a C program to print the mark sheet of n students using structures.

Algorithm


Step-2: Read the number of students n

Step-3: Setup a loop for n students

Step-4: Read Rollno, Student name and six subject marks

Step-5: Calculate the total and average

Step-6: If any one subject mark is less than 50 then grade = fail

Step-7: If average>=75 then grade=Distintction

Step-8: If average=60 then grade=Firstclass

Step-9: If average=50 then grade=Secondclass

Step-10: Print all the student details

Step-11: Stop.

Program

#include

struct class

{

int rno,m[6],tot;

char name[10], grade[12];

float avg;

}s[10];

main(){

int i,j,n;clrscr();

printf("Enter the number of students : ");

scanf("%d",&n);

for(i=1;i

scanf("%d",&s[i].rno);

printf("\nStudent name ");

scanf("%s",s[i].name);

printf("Enter 6 subject marks : ");

scanf("%d%d%d%d%d%d",&s[i].m[1],&s[i].m[2],&s[i].m[3],&s[i].m[4],&s[i].m[5],&s[i].m[6]);

s[i].tot=s[i].m[1]+s[i].m[2]+s[i].m[3]+s[i].m[4]+s[i].m[5]+s[i].m[6];

s[i].avg=s[i].tot/6;

if(s[i].m[1]

Enter the details for student 3 :

Rollno 3

Student name suji

Enter 6 subject marks : 45 56 67 76 72 56

Student Mark List

R.No Name Total Average Grade

====================================

1 kavi 495 82.000000 Distinction

2 prabu 549 91.000000 Distinction

3 suji 372 62.000000 Fail

Result

Thus the program for printing students mark list using structures was written and executedsuccessful.

Ex.No:19 EMPLOYEE DETAILS USING FILES

Date:

AIM :

To write a program of employee details handling file by using fscanf() and fprintf().

ALGORITHM

Step-1 Start

Step-2 read filename

Step-3 open a file, filename

Step-4 read n

Step-5 Set a loop to get name, salary and age

Step-6 read name, salary, age from a file

Step-7 print name, salary, and age into the file

Step-8 close file fp1

Step-9 End

PROGRAM

#Include

#Include

void main()

{

FILE *fpl;

int age,i,n;

char filename[25],name[25];

float salary;

clrscr();

printf(Enter the file name : );

scanf(%s,filename);

fp1=fopen(filename,w);


45/47

45

printf(Enter the Number of employee : );

scanf(%d,&n);

printf(Enter the Nae, Salay and Age:\n);

for(i=1;i< =n;i++)

{

fscanf(stdin,%s%fd,&name,&salary,&age);

fprintf(fp1,%s\t%f%d\n,name,salary,age);

}

fclose(fp1)

fprintf(stdout, \n\n)

fp1 =fopen(filename,r);

printf(name salary age\n);

printf(\n);

for(i-1;i< =;i++);

{

fscanf(fp1,%s %f %d,name,&salary,age);

fprintf(stdout,%s\t %8.2f\t %d\n,name,salary,age);

}

getch();

fclose(fp1)

}

OUTPUT:

Enter the filename : vrb

Enter the Number of employee : 3

Enter the Name, Salary and Age:

Venkat 10000 24

Ragu 15000 29

Shankar 20000 32


46/47

46

Name salary age

Venkat 10000 24

Ragu 15000 29

Shankar 20000 32

Result:

The employment details given using files successfully.
